Some people get battery life less than others and the simplest most common answer is the battery calibration. There are so many other reasons to take into account from having defective unit to what are you using your phone for. people spending more time on light apps such as simple chat app will get alot more screen on time compared to other who spend more time playing heavy 3D HD games. Additionally, wifi, 3G/4G, GPS, auto sync, bluetooth, NFC and brightness of the screen will have an impact on the battery life thus screen on times, so you should take into account all of these things. Comparing screen on times is useless as you don't know what the other person was doing during the screen on times and what other things were on.
Therefore, I decided to make this topic. I saw people complaining that their screen on of there phones is alot less than others, although they have all other services off and brightness to the minimum. before going into calibrating your battery, you should check whether your phone is going into deepsleep as expected or not. If not then this is what is draining your battery, you can use wakelock apps to check if any thing you installed preventing your phone from going into deepsleep.
Apart from previous reasons, calibrating your battery could be the solution. First, you should note that you need to do this once every ~2 months (avoid doing it alot). There are so many ways to calibrate your battery, and I will mention two here:
if you are rooted:
1- run down you device's battery until it turns itself off
2- charge it until it is 100%
3- use any app from the play store to delete batterystats.bin
4- you can stop here but the following steps will speed up the calibration process
5- repeat step 1
6- charge it fully without pause
7- use your phone normally and the battery will improve in the next few days (steps 5&6 should speed it up)
if you are not rooted:
1- run down you device's battery until it turns itself off
2- charge it fully without pause
3- turn it on
4- wait few minutes
5- charge it for one hour
6- use your phone normally and the battery will improve in the next few days (repeating 1&2 should speed up the process)
if anyone has any suggestion or comments or if I made any mistake please let me know.
please hit thanks if I helped in anyway
What to do after calibrating your battery?
now you calibrated your battery, you need to understand few things to squeeze the most out of your battery. the basic answer is to monitor your battery and avoid things that drain your battery. so what uses more battery, I will but list of things that use the most battery in order (what use the most to the least). The list came from me monitoring every single one alone (it might not be accurate)
1- Processor
2- screen
now people would say that screen uses more than processor. In order to test this, charge your phone to 100% unplug it and directly play heavy HD game for 30-60 min and go and check battery stats, you will see the game no.1 then screen no.2. the problem with the processor is that when it heats up, it wastes ALOT of battery as the heat is just energy came from the battery. if you want to extend you battery life, you should start with these two as they use more battery than everything else. To make it simpler I would say 1 hour of screen on uses battery enough to keep your wifi on for >1day (and I mean wifi not the whole phone with wifi on)
Recommendations:
a- avoid using apps/games that heat your phone (most games does, but try to avoid when possible)
b- Avoid using your phone while hot (this will degrade the battery and the screen and will hurt other internals such as processor in the long run and will also waste too much battery)
c- underclock your processor if you play to much heavy games (to protect your phone from heat and extend battery life)
d- reduce the brightness will save you good few hours of use
3- auto sync
4- 3G/4G
5- wifi
I put auto sync first because in order to have working auto sync, you will need wifi or data + processor to process what are you syncing
6- GPS
GPS actually consume more battery than wifi when both are working, but the good thing about GPS is that if it is not in use even if it is on, it doesn't use battery unless it was needed to locate the phone.
Recommendation
Turn them off when not needed. There are certain apps in the play store that turn off wifi, data and auto sync when screen off then turn them back on when screen is turned on. I use tasker which does this and check for downloads before turning off wifi or data.
you are more than welcomed to add any tips or make comments or suggestions
Are you sure you are talking about Xperia Z1 and not lets say Nokia 3310? You should not overcharge modern batteries, as they dont have the memory effect. In realoty discharging it to 0% and charging to full will actualy make battery worse and cause decrease of battery life. You should also avoid charging overnight if you want to keep your battery in good condition. The best thing to do is to keep it between 15% to 85-90%, and dont let it discharge/overcharge.

I do understand what are you talking about and I do know about battery memory. But you still need to completely discharge your phone once every ~2 months for calibration purpose. But you are right about overcharging it. I will modify the main topic to make these changes, Thx

No you don't, that's completely unnecessary with modern batteries.
Also, wiping batterystats.bin just clears the info in the battery usage page in settings, it gets wiped automatically every time you charge over 90% and has nothing to do with calibrating the battery.
So much misinformation in this thread.

you could have said it in a better way. any source about what are you saying?. There are tons of sites that agree with what I said, a quick search found this
http://gizmodo.com/how-to-take-care-of-your-smartphone-battery-the-right-w-513217256/1416982678
at the end they said this
"To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible. For the most part going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often. That said, it's smart to do one full discharge about once a month for "calibration," but don't do it all the time. Running the whole gamut on a regular basis won't make your battery explode or anything, but it will shorten its lifespan."
and regarding wiping batterystats.bin. There are tons of articles and apps the recommend this and so many people said that it helped them. it is not just useless because you said so, unless you have strong evidence which I want to see.
This is old advice. With the new technology batteries it is not advisable to completely empty the battery.
There is no need to "condition" the batteries and they do not suffer from "charge memory"
Plus, there is already a thread in this forum about battery handling and tips

I'm within my 30days
I love this phone.
My battery discharges rapidly, especially their the first 5 mins off the charger.
I have been looking at this issue, but I am new to android.
I find it funny we can't actually see a battery percentage without installing third party apps. Then Sprint tries to say that these apps are the cause of the issue.
Trust me, I understand that this phone will drain the battery more rapidly than a lot of other phones. But there is something wrong with the way this phone charges the battery, therefore we see less battery life.
Can anyone prove or disprove their little claim that I am killing the battery by looking at its performance?

tell him that the phone and the plan is also draining your wallet, may be you should do something about that too
the reason your battery sometimes drops so quickly after you take it off the charger has been well documented. several threads with ways to improve the battery as well.
it has to do with the way the battery actually charges. it charges to 100% then allows the phone to discharge to 90% then charges up again...so at any time when you unplug the phone you may have 91% to 100% charge. or something like that.
1) have you tried conditioning your battery? (plug, wait, unplug, rinse repeat)
2) are you rooted? (try using something like SetCPU or JuiceDefender)
3) are you on stock or custom rom? (the custom kernel devs have been working on this issue)
hmmmm...how could you possibly disprove the sprint person? try not using it for a couple days...see what happens.

No doubt....my withdrawals kick in after its been in my pocket for too long...
While do appreciate the input, I disagree with it being well documented. I have tried both top off methods, aka conditioning, and it seems to give you more of a charge, but as soon as discharge the battery you are right back where you started, conditioning the battery every morning is not ideal.

If the phone is new, its going to take a few cycles to improve. I remember when in my first week it wouldn't last a day. Now I can get 20-30 hours out of it. (ROMs and tweaking of course.)
There are tons of threads detailing what you can do to improve battery life... What have you done?
The purpose of a battery graph is to compare how your phone discharges to how your phone is being used. What plotting app do you have?

This is false...lithium batteries do not get broken in or conditioned. What you saw is more than likely a result of constant using your new toy. The novelty has worn off and you have tweaked it so now you have extended the battery life.
I have disabled Bluetooth, WiFi, gps, and 4g
I set the radio to cdma only, and this led to problems. So I cleared all data And started over.
Are youguys seriously ok with 'conditioning' your batteries every morning?
Sometimes I think people think I'm just trying to find faults with this device. I want to keep the phone, but I also want this problem clearly identified and resolved. I should not have to use my tilt 2 to charge my battery because my new state of the art phone can't do it correctly.

it's called the Fat Wallet Mod Discussed in other threads also,
But yes, I think it's dumb to have to condition the phone to get the best battery life, and how I have to get soo much good Light to take a good camera shot when other comparable phones don't need too. You have to weigh the goods and bad yourself.
The discharging of the battery is necessary as trickle charging a lithium battery is not recommended...thus this leads to you possibly having 95% instead of the full 100%. This is normal. Just unplug the device and charge again, or top it of in the car.
You never mentioned if you were rooted or not. If you don't use the news then don't sync it. If you don't use gtalk then disable it and turn off the auto sign in...i found that this app uses a lot of battery and its turned on by default.
It is not conditioning your battery.
When you charge your new evo and it hits 100%, the phone STOPS charging. It has no trickle charge. It begins charging again at 90% if still plugged in, although it reads 100% until it comes off the charger.
SO, when you unplug it, it says 100%, but could be anywhere between 90 and 100. If you simply unplug your phone, wait for it to display something other than fully charged (usually takes 30-60 seconds), then plug it back in, it will then charge back to 100%. You can simply unplug it, wait a few and then plug it back in while you go about your shower and cereal. When you are ready to leave the house you'll probably be at or near 100% instead of seeing it drop to something much lower.
This is NOT conditioning your battery. A more appropriate term would be "bump charging". As you are simply bumping it back to a charge state when it was in a resting state.
Another GREAT method of increasing battery life is resetting your battery stats. This is clearing out what the phone defines as full, and as empty and setting up these values again. I am not sure why, but they are off on many phones. They also get wiped anytime you flash a new rom so this procedure would again be in order if you experience poor battery life.
These are the instructions straight off cyanogen wiki. You can also reset them using Amon recovery.
Battery recalibration
If you're experiencing higher than normal battery drain, try the following:
1.Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2.Boot to recovery mode and go to console (or adb shell) and type:
mount -a
rm /data/system/batterystats.bin
NOTE: Newer Amon_Ra and ClockworkMod recoveries have an option to delete the battery stats, do this in place of the console commands above.
NOTE: To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for CM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue with this troubleshooter.
1.Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off.
2.Recharge the phone completely and then use as you normally would.

sprint rep is an idiot and if you took the time to search instead of making this post you could have saved yourself some trouble
no...i can't imagine anyone 'conditions' their battery daily. however, if experiencing issues wiping the stats and doing the conditioning thing do have an impact.

While most of the battery problem isn't the plotter app, the plotter app is using a fair amount of battery, so I usually would recommend not having such apps running except when you are diagnosing problems. Turn off various apps sync settings and keep background apps to a minimum, like juice plotter, battery widgets, and other data intensive apps and widgets. That right there will save you some power. Other than that, follow all the excellent suggestions that are already in this thread. Oh, and I find I get better battery when I just don't worry about it. I set up all my sync services and then leave them alone. Then just go about my day, using my phone as needed. Constantly worrying about it only wastes power because you are constantly fiddling with settings and apps.
PROTIP: Never believe anything a cellular rep tells you. Ever. EVER!
The Evo just has terrible battery life, that's my personal conclusion. One of the trade offs with such a huge screen and such. You'd think that in this day and age battery technology would have kept up with all the other bells and whistles, but no.

I'm sorry but that all sounds like the formula to derive the circumference of the nucleus of an atomic variable perpendicular to the perimeter of the nth root in relation to the isosceles of the .........geezus, all that just to get a smidgen of decent battery life...
Hi!
I am going to buy a Huawei U8800 soon but I am wondering about the battery time, how good is it?
Could you please post a report over your usage and how long the battery held.
Thanks!
// Sebgus
Pretty standard for smartphone.
With heavy use - from charger at morning, to charger at evening. With easier use battery will last for 36-48 hours.
And then I guess you use apps like facebook & twitter that updates all the time?
EDIT: On the homescreen I meant
I may have a faulty unit, but my battery time on my X5 is bad, almost to the point where I want to sell it.With a full charge,GPS,Bluetooth and WiFi turned off and minimal usage throughout the day I'm at 10% by 8pm.
power121212:
That doesn't sound that good! But it seems like the quality on the batteries shipped with the U8800 shift very much? Some get a decent 2 days with normal usage and some are fully charged in the morning and then almost empty at the evening.
Shouldn't warranty cover that?
I would like more reports please, want to figure out how good quality they have. Maybe can do a template:
Date on purchase:
Batterytime w normal usage:
Activities, normal usage (what did you do):
Batterytime w heavy usage:
Activities, heavy usage:
Thanks!
I'd just like to point out that you CANNOT rely on the battery meter to give you an accurate reading for the battery capacity. If your phone drops a few % very quickly then you need to remove batterystats.bin and power cycle the device a few times. Initially when I got mine it went 'flat' quite fast telling me to plug in but when it hit 0% it then shot back up to 30%, since the remaining capacity would have been recalculated.
The battery life is good. It is a large battery for this size of device (1500mAh) the HTC Vision has a 1300mAh (more or less the same hardware). Just be smart about how you use it, don't keep over 9000 widgets on you home screens terminate apps completely, don't leave wifi/gps/3g on unneccessarily (it only takes a few seconds to reenable them in settings)
I agree to Poulsen8r .too much running appz on your phone may cause the battery empty fast.I suggest to monitor all those running appz and turn it off if unneeded.

Agree. And it greatly depends on your location as well, I mean your battery would definitely last longer if u're sitting besides a strong cell tower all day without finding, detecting and re-connecting cell towers.

Make sure your phone is fully charged and plugged into pc then:
start terminal/cmd
adb shell
rm /data/system/batterystats.bin
reboot
Unplug your phone and let it discharge WITHOUT TOUCHING IT as long as possible ideally until its empty. Then charge FULLY and discharge again. Then it should be fairly accurate and consistent (no sudden drops pf 10% in 10mins).
theres an app here in xda that helps to do battery calibration:
http://forum.xda-developers.com/showthread.php?t=1024867
Rooting, SetCPU and the battery calibration-app feels like a must-have!
Thanks
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )
That's all folks! Please report your success / lack of such here. Also, feel free to ask questions, and I along with other users with answer them according to our ability.
I will later add a section on "good practices for battery usage" with tips and tricks.
Cheers!
Attached are screenshots of my results after calibration: This was under moderate usage. Pretty damn good if you ask me.
Post-calibration methods of improving Battery Life
Updated: Post#2 will explain how to solve battery drainage problems when recalibration wasn't enough. It will also explain how battery reporting works, common practices, tips, tricks, etc.
Battery Tips / Tricks / Common Practices
Important things to know:
1. It's important to understand how battery indicator on Android works and how Android manages / reports your battery life. Please read this article:
Your Smartphone’s Battery Gauge is Lying to You (and it’s not such a bad thing)
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
2. Li-ion batteries used in modern smartphones don't have "charge memory". Partial charges won't hurt the battery (e.g. charging from 60% to 80% or from 10% to 50% etc). Feel free to give your phone small charges whenever you have time and need the phone to last longer.
3. Smartphone batteries don't like to be completely discharged or to be kept at 100% capacity for extended periods of time (this actually damages batteries over time). But worry not, the battery software prevents this from happening for you. That's why some of your phones never get to 100% or drop from 100% to 90% minutes after you disconnct the phone from a charger.
4. All batteries gradually lose a small percentage of their capacity after a certain amount of charge cycles. It's a natural part of life. It's always nice to have a spare battery or to purchase a replacement when your current battery isn't to the task anymore.
5. Don't pay much attention to the battery %, just use your phones. I know it's very tempting to track your battery usage every 15 minutes and try to find problems. Been there myself. Thing is, if you do this, you might start thinking you have problems, when you don't have any.
Bottom line - just try to use your phone and not mess with the battery unless problems become really apparent.
------------------------------------------------------------------------------
Other proven ways to improve Battery Life
If you have re-calibrated to a full capacity (4200mv) but your battery still drains terribly - follow these steps to pin point the problem.
1. Find which app / process is draining the battery.
If you get lucky, the infringing app will show up directly under the stock "Battery Usage" statistics. However, in most cases "Battery Usage" isn't very informative. Most people report that they only see "Phone Idle" consuming most of the battery without much insight into the details.
Things to do:
- install Watchdog, go to preferences, set CPU threshhold to 20% (or even lower if it's not enough), check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20%(or even lower if it's not enough) as well. Run it for a couple of days.
If you start getting frequent Watchdog notifications about a certain app breaching the threshold - uninstall it, find an alternative.
- install BetterBatteryStats from here -
http://forum.xda-developers.com/showthread.php?t=1179809 run it for a couple of days and monitor apps / processes that are using up more wakelocks than they should.
Once you find the infringing app - uninstall it, if it's a process - find out if it's safe to stop / freeze before doing anything.
2. Freeze bloatware aka "stop the problem before it becomes a problem."
Unless you are running CM7, your rom is based on stock 2.3.4 and still has blur in it. Blur apps and processes might be running without you even using them and sucking out precious batter life while they are at it.
Things to do:
- Get TitaniumBackup, freeze all bloatware that is mentioned as "safe" in this thread -
http://forum.xda-developers.com/showthread.php?t=1182663
Use your phone for a couple of days afterwards and watch for improvements.
If these software tweaks aren't enough, the problem might be with your system setup. Go through these steps which should hopefully fix your setup in favor of awesome battery life:
3. Flash a custom kernel, set up battery saving profiles.
Many people have reported success with this step. Custom kernels are not just for overclocking. A custom kernel with smart profiles will definitely give definitely extend your phones operating life during the day.
Things to do:
- Get a custom kernel., the popular choice on here seems to be faux'es kernel, so I recommend it -
http://forum.xda-developers.com/showthread.php?t=1156040
Get one of the battery saving SetCpu profiles along with it. Basically, a good battery saving profile looks something like this:
- absolute minimum CPU clock with screen off (something like 275 Mhz)
- lowering CPU clock with temperature > 50C (something like ~800Mhz)
- lowering CPU clock when battery < 30% (something like ~800Mhz)
Many people reported success in using such profile for lowering "Phone Idle" drain.
4. Flash a different radio.
WARNING: Be extremely careful with this. Flashing a wrong radio is the right way to hard brick your phone.
Although some people are reporting to have fixed battery drainage by trying out a different radio, I seriously wouldn't recommend going on a flashing spree unless you know what you are doing.
My advice here: flash the latest 2.3.4 for your carrier if you haven't yet. From there on, experiment at your own risk.
5. Disable Data and Wifi when idle either manually or with an app."
I seriously get surprised every time someone says they have a horrible battery life, when they keep an internet connection on at all times. Constant data always = battery drain.
Things to do:
- use apps like Green Power to disable data / wifi for you when you are not using it
- learn to turn off your internet connection manually
6. If all else fails - start over from scratch (read: clean install a rom).
I've heard reports of people getting better life with Froyo than GB, or that a specific custom ROM solved their problem for them. A million dollar question: if it works for you, why not use it?
Things to do:
- try a ROM without blur, like CM7
- try Ninja Speed Freak (developer and many users reported great battery life)
- if battery life is your top concern - try Froyo

Are you using stock Orange 2.3.4 rom?
If yes, your Rom might not have the battery jumping problem. You can still use this guide without the battery fix to recalibrate.
Let's wait for someone with Orange 2.3.4 to confirm if jug6ernaut's CWM battery fix can be used or not.
Indeed, I have not the battery jump issue, but I'm exprimenting some weird behavior...
like when I restart the phone, it shows about 10% higher than before. I tried this multiples times yesterday. When it was about 40%, it starts to drop suddenly, 'till it got to 18% and get back to normal decrease to 4%, 2~3 hours later...
See the images attached, the red circles are the times I rebooted it and the blue arrow is when it drops suddenly...
Question on step 4. To confirm, we shouldn't click on anything in BatteryCalibration, all that needs to be done is take note on the MV number, correct?

Did it only start doing this on 2.3.4 or you haven't checked before? Anyway, I would do the calibration to see if it changes anything.

No clicking in step 4. Just write down or remember the MV number.
Yes it just starts when updating to 2.3.4... In the first days I got the impression of lower battery level, so reading the forums I saw the restart/level change problem, and tested it

You probably updated to 2.3.4 while not at 100% battery level, and it messed up your battery stat. So, yes, do all the steps in this guide except for jug6ernaut's battery fix part.
thanks, ill give this a shot....again.....tonight and hopefully it will fix my issue.

I'm on a rooted stock GB and I'm having the problem where the battery usage stats are inaccurate and won't got below 90% after using it all day. This all started after I used Battery Calibration. Do you think that this would help correct the problem?
Edit: Also, would I need to complete all of the steps including the CWM part? I haven't flashed any roms yet, so I don't know if this would be necessary.

Seems like you used Battery Calibration while not at 100% charge and your battery stats got messed up.
The reason I recommend using CWM is because the battery stats file is created on each boot. So, with my instructions you can charge the phone to 100% while it's off and wipe the messed up stats before it boots.
You can try using my instructions, without the CWM part, except you need to wipe your battery stats with Battery Calibration app after step 4.
lol i left pandora on since this morning and its only at 67%. ugh, when i wanna force drain the battery it goes slow as hell but when i wanna conserve battery live for usage it drains quick. hahaha.
I just flashed navalynt's πCrust rom fully charged, cleared stats through cwm, booted and now i'm close to 3days.

Yep, that's why flashing only when at 100% charge always pays off.
I get the same results by booting to CWM, wiping battery stats, rebooting, starting Battery Calibration, plugging phone into wall charger, charging to 100% (4197mv for me), and then calibrating with Battery Calibration. I start this process at any battery percentage, and have been doing this for a long time now. I have never had to deplete my battery until my phone shuts off, and get great battery life.

After the calibration I had 4200mv, so it seems like you are doing things right in regards to the battery.
"Taking the battery out and putting it back in" trick works wonders though in restoring battery life to maximum state (if you had it decrease for some reason). I've tested it multiple times even back when I had the Milestone.
First to clarify my question: I'm not asking how to prevent the daily battery drain in a poor-signal area. It definitely happens unless the phone is switched to airplane mode. My question is how to avoid the shortening of the battery life in the long run if the phone has to be used in such condition.
My workplace is basically a signal black hole to any carrier. With T-mobile I got no service for most of the time but I can occasionally send/receive text messages/emails say every 15 minutes with flimsy connection. There is absolute no way to make a phone call, so I usually walk outside when needed. I don't have WiFi neither so I prefer to keep the phone on to stay on the grid. However my concern is doing so will shorten the battery life eventually due to the constant power draining and recharging, so I come up with some ways for such condition. Please suggest which you think will do the least harm to battery and allow me to receive email and text.
1. Use it normally. It usually consumes 60% of the battery just sitting on my desk throughout the day. I can actually live with it be cause the battery is large enough for me to waste this way. But it harms the battery life without a doubt.
2. Use it with a charger plugged on my desk for most of the time, so it will supply the power for signal searching. Usually if you keep a battery at full charge all the time, it dies soon due to "slacking." My laptop has this problem and its battery basically serves as a UPS now. I have less concern for a phone because it will still be recharged daily.
3. Use an NFC tag to tell the phone it's in the office, and then use some software to prevent the draining like Tasker/Juice Defender. That makes most sense but I haven't have figure out the profiles. I've used Tasker before (thought it's too complicated) and NFC is totally new to me. I would like to take some suggestions if you have done something similar.
Thanks!

Isn't the issue with batteries related to cycles? I'm not sure it matters that you end up with 40% of battery at the end of the day vs 15% when you charge it up. A cycle is a cycle, more or less I think.
If you don't believe the first point, I also don't think that research really shows that leaving a lithium ion battery plugged in "all" the time has major detrimental effects, and even if it did you would still be using the battery for a good deal of the day, at least the time you're not at work right?
I feel like you might be a little too worried about it.

About the charging cycle, I read something here: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries. Basically it shows deep charging cycles has more detrimental effects on the battery capacity. My point was if the battery is cycled deeply everyday, it is under much more stress compared to those working with good signals.
Maybe I worry too much but I feel really bad just to see my phone sitting there wasting a lot of battery.
I have had the same problem with you as my office is underground.
From my experience, it's best to turn off data. You can turn off the radio all together, but I guess you still want to have signal where you can.
This can be automated by Taker (haven't used) or Juice Defender. I don't know if Juice Defender Free can do this (it should), but Juice Defender Ultimate have an option to turn off wifi and data when the screen is off.
Having the charger next to your desk is also a viable option. But rather than plugging it all the time, you should charge when it is needed.
Edit: as discussed elsewhere, you should not try to do full charges (0-100%) as this would not work out well for you at office as well as it it will shorten battery life.
Edit 2: Juice Defender Ultimate
=> Enable Advance profile (Status Tab)
=> Go to Control Tab
=> Enable Mobile Data and Wifi control (first and third option)

Can you try only charging your phone at work? From the options you've listed,leaving it plugged in seems like the best option at work seems like the best option. Assuming you currently only charge your phone once a day, it shouldn't make much difference to switch the charging time to during the work day.This way your peak energy usage will fall on a time when you have unlimited power available and you should have enough battery to go home and come back.
build.prop tweak
There is a build.prop tweak but I can't guarantee that it works.
You can try it out and tell us about it :fingers-crossed:

#improve battery under no signal
ro.mot.eri.losalert.delay=1000
The number value is how often to re-connect to the tower. A phone in a poor connection area will
attempt to reconnect all the time, draining the battery. It's in milliseconds so 1000 = 1sec. I wouldn't
exceed 2sec but you already knew you are on your own with this one.
I have the exact problem at work.
My question is if I connect the phone to the charger at work, will the phone runs on the juice from the charger or from the battery? If it runs on the juice from the charger (like laptops), that should have minimum effect to the battery. If it uses the battery and the charger just charges the battery then the battery life will be cut in half (2 charge per day instead of 1 charge per day).
I have terrible signal at work and my Inspire has a small battery. My phone is in power save by lunch. I charge mine during lunch every day and leave it on the charger at night. I generally will not plug it in if I can't charge it all the way up. My original battery is now 18 months old and works as well as it did new. Other Inspire/DHD users have had to replace batteries in less than 12 months, so I don't think my charging cycle variations have harmed it too much.
It only has to last until after the holidays when I can order my N4. Even if I had to try to push it to 2 years, I think I wouldn't worry too much.
Also, by the time it is not under warranty, the batteries will be cheap and will always be easier to change than an iPhone.
Sent using the power of the dark side.
Thanks everyone. Based on the discussion I think I will just use it normally and charge whenever needed. The phone should be my slave not the other way around. I'm not planning to root it, at least not now, so I won't change the build.prop.
I did tried Juice Defender yesterday. It slowed down the battery drain but not very impressively, because it only turns off the data not the entire cellular radio. I installed the app during lunch so you can see the difference from the middle of the day. Google+ was a real ***** because it tried to upload my camera photos with such connection... I turned it off too so it also helped.
"Android OS" should not be this active.
It's possible that you have some background process draining the battery. Try disabling as many services as you can.
If you have Wifi at work try turning it ON. If not then turn your Mobile Data OFF like KyraOfFire suggested.
I get weak signal at my work as well. Thankfully, we have WiFi, so I usually force my phone to use 2g then connect to WiFi. :good:

I don't have Wifi unfortunately. I will look into Android OS later on.
If you're looking here you might be struggling with terrible battery life after the mm update. The first couple of days and few complete cycles after my update, I was getting less than 3 hours sot, in less than 12 hours, whereas lollipop treated me much better, approximately 5-6 hours sot in 24 hours. Let me clear some things from the very start: I am not attempting to create perfect battery life by sacrificing radio speed, disabling wifi when asleep etc. I'd rather have lte whenever possible and I only stop the radios at night between 11pm and 6am, using the tasker-like app included with z5.
I will continue by explaining a little bit more thorough how I did my update and in next post will give the exact steps to follow so if you're in a hurry or only here to find tips on improving battery life, head there right away. Also, if anyone has other ideas on how to improve on battery life, don't be shy and chip in.
So, since this is my first unrooted android phone ever, I had to adjust a little bit. Where previously I was using a combination of apps such as tasker, secure settings, greeenify, logcat and BBS to diagnose wakelocks and the like, I found that when I first tried to improve on lollipop battery life with these tools, actually I worseend the battery situation. For instance greenify would stop apps so they would take more cpu cycles to start again, etc. The z5, as it is, it has awesome right from the shelf standby capabilities so I feel root for those reasons only is not that sought for, after all.
Marshmallow update
I installed the nordic combined fw with clean wipe of all options present in flashtool. Afterwards I started the phone and let it restore the apps via google backup. At this step you might want to get rid of unnecessary apps (I had quite a few of them). I let all the updates happen, then I headed back to the pc and sony pcc to restore my backup (I know some people recommend starting fresh with the apps but I am the kind of lazy person, and really spoiled by titanium backup, but well, since i cannot have the latter..). I specifically chose to restore the apps data.
After restore it might take a while for the phone and whatever apps you have to sync with their respective cloud and data. I would only mention that although I kept google photos for now (with no auto sync yet) I am rather using the sony memories cloud, it seems to me faster and more standby and mediaserver friendly. So I had some problems with photos but will try it again, maybe it works better in mm.
I haven't disabled a lot of the bloatware, actually I advise you to go slowly and carefully about that since in lollipop disabling some of the preinstalled apps result in random reboots.
What I did though, after the first (horrible) battery cycle was to clear all app cache: settings/storage/internal storage/cached data
I also disabled location scanning under settings/location menu
I also performed a battery re-calibration which you should do anyways once a month or so by letting the device deplete completely (1-2% really) shutdown, charge in the wall charger up to 100%, start it plugged in charger and verify that battery percentage reads 100%, then unplug.
I didn't take a screenshot of the 3 hours sot I got a few days ago, but here are some screenshots of the much improved battery life, second day of 6+ hours. Let me tell you I didn't go easy on the battery either: few hours of listening to flac from ext sdcard in poweramp or google play over apt-x bt, couple minutes of hangouts, few sms, lots of tapatalk/reddit, a bit of camera, in other words, kept radio lte almost the whole day (while at work), all with adaptive brightness at halfway mark
steps
If coming from complete firmware reflash, you really got to let the phone 'settle' ie, sync your emails, photos and what not cloud services you sync with. When mediaserver usage decreases in battery usage you should be fine for next step
Delete all apps cache
Optional, if you have root/recovery mode you might be able to delete system cache
Optional, disable location scanning
Calibrate battery (you really gotta do this periodically)
I would add, as some sort of maintenance procedure, don't let your phone become too hot as that not only drains the battery faster but can permanently damage the battery, ie reduce its life/capacity.
There are also other ideas that I am currently trying, however as I am not sure they help or even cause problems of their own, will mention them later on when I'll have tested it more thoroughly: it's about debloating, usage access and others

Some apps might not very well compatible with MM and draining. After a clean flashed I managed to get a good battery but after installed all apps the battery is a bit worse now.
Same observations here. Not a quality update for the moment. Having some problems with fingerprint unlocking. With lollipop I didn't encounter this kind of problem.

This is how to improve battery thread so don't start the crap about what you don't like in MM.
I think trickle charge might be an issue for some. When it's been charging for some time and at 100% unplug and plug the charger back in a few times

The post says brightness halfway brightness slider (with adaptive display).
It's been a while since this post and a couple MM builds. I think that the battery calibration is still a good procedure towards experiencing better battery life, so I'd do that every month or so. Otherwise, look for more obvious issues. Just the other day I noticed a new --and very well rated-- social app I used for a few moments then, half an hour later it didn't let go of the location, even in background, exited with back button.

Without having timed it precisely, my ballpark numbers put it within same previous battery performance.
IMO, z5 is good enough for light to moderate usage, even some gaming although not expert on that.
It is good also for standby time (I keep on all location scanning that you might have, google now active etc), music listening ,etc.
What depletes the battery pretty fast though are any camera-related action/video recording, hangouts videochat. The camera also overheats quite rapidly so there's that.
