ok ive been reading a few post and ideas on the net about battery life and how to get more and something that ive noticed is that if i run my battery to say 15% and give it a full charge over night it makes no difference if i just give it a couple of hours charge.?
in fact im sure it seems better on battery when giving it short charges?

it doesen't matter if you leave it over night, or just a few hours.
if the battery is full, then its full.

Well, just to be correct. "Full" on your phone isn't a full battery. Full is reported between 95-100%. That's FULL for your phone. It's not possible to keep the phone at a 100% charged state always without hurting it. So it can be between 95-100% to be full on your phone.
I don't want to open a new battery thread, so i'll post my problem here.
I set up an e-mail account (exchange) a few hours ago. Always had Problems with Android OS, ofc. But guess who is the new primary consumer? E-Mail.
Can't believe that, never had any problems with gmail. I'm going to delete the exchange account and hopefuly it will be ok again.
Anyone else having issues with exchange?
Cheers

here is the screenshot.
email will kill your battery if it is set to PUSH all the time, and if you are getting large mails or too many of them. Make sure you think through push vs timed sync, and also configure how much of a message you want to retrieve (if it is a large message). Still the more emails you are getting the heavier this will drain the batt. I have no idea how Email client eats much more battery than Gmail. I believe it is because gmail's usage is not 100% shown under "gmail", it may be attributed to some other system processes. At the same time, the email client is heavily customized by Samsung, so who knows.
The mail account was brand new, so there was only one mail on it.
I disabled it, and the drain overnight was about 10%, so i just stay without it.
Cheers
Speaking personally, I have push email (Exchange) on all the time, along with WiFi, Bluetooth and data.
I have just conducted a 24 hour experiment and with low to moderate usage of the phone (2 hrs 37 mins screen time) I had 45% battery left. This includes time at home, time in an office and time outside.
I know this won't help those who are struggling with battery life but it does underline the inconsistency of performance of battery on these devices in certain conditions and it absolutely highlights the dangers of trying to attribute all performance issues to a single cause. Fast Dormancy and Latitude were the two biggest battery wasters in my case and performance has improved significantly since I turned these off.
In my view there is no single once-size-fits-all solution; a new firmware might alleviate the issues for most, but it could even be that a batch of rogue hardware components might account for the big discrepancy between users like me, who would claim excellent battery life and others who see their phone battery wiped out in just a few hours.
All I can say s that it is reasonable to expect - and perfectly possible to have - all the toys on our phones on and working, and still have decent battery life.

enable ur power saving mode always

Got a NC for xmas and rooted it and installed cm7.1 and everything seems to be working well except the battery. I went under battery use and i see that Display is eating about 60% of my battery! I turned brightness down to 25%-ish and i have also turned off everything i am not using but the problem still persists. I have seen people saying i need to do some kind of battery calibration but i do not know how to do this. If someone can help me get this issue resolved it would be greatly appreciated.
Unfortunately, you can only do so much about screen battery consumption. Turn brightness down as far as is comfortable, but personally, I don't want to give up the vibrant display. I find 25% is usually adequate indoors. With my screen ON, it consumes roughly 10% per hour of use, which equates to 8-10 hours of use -- not bad. With the screen OFF, it sips less than 1% per hour, and often less than that over a few hours.
Keep in mind, you WANT screen battery consumption to be the largest value. That means it's nice and idle when you're not using it. If something else is using a significant amount of battery, that may be something you can do something about.
As to calibration, I do find that Android battery gauges often are incorrect until you let the battery completely discharge from a full charge once. Then it's calibrated correctly. Of course, that's not recommended for battery health, so don't do it compulsively. I had a device that showed 1% battery remaining for 3 hours while I played MP3 audio.
I wish i was getting 10% an hour, im getting roughly 20% I now have another issue that i did not have this morning, i can not connect to my computer via USB. Is there a setting i might have turned off in my fit to increase battery life?
@Lsjreadingpa Renaming /system/app/phone.apk to phone.bak is a commonly undertaken act that can significantly lower battery usage. Also, you can turn off Account Sync when not using it actively, as it increases battery drain when you are not actively using the NC.
As far as the USB is concerned, make sure you have USB debugging checked in the settings menu.

How do i rename it? Also a bit of an update, i have turned off syncing as well as alot of the other options and i am losing 5%/20min
Last night I cleared cache and battery stats and let the battery die and then charged it to full this morning. Like I said above I turned off syncing and gps as well as removing beautiful Widgets. I just don't know what else to do. I'm attatching two screenshots showing my battery use in the last hour.

You can use Spare Parts to check what's consuming battery if your DOMAIN supports it.
Anyone able to help?
Are you concerned about battery consumption while you're using it? If so, then your brightness and the applications you're running are going to determine your battery life.
If it's battery consumption while idle (screen off) that you're concerned about, then do you have any widgets that do network access? I found that my battery life dramatically improved when I was no longer using the Twitter widget.
In Spare Parts you can go to Battery History, then check 'Partial Wake Usage'... this can help you figure out if there's an application that's preventing the device from going to sleep.
I would recommend trying a newer nightly or the Mirage/Kang build found in the Android Dev sub-forum here. I forget when they were added, but there were a few big improvements to CM7 a while ago to help with battery life.
Battery consumption while using it is kinda of scary because it drops like a brick. While sleeping, which i don't think it was doing, seemed to get better after i removed beautiful widgets. How different is the Kang build?
The Kang build has an updated kernel and other updates since the last CM7 nightly. It's supposed to fix an SOD issue. I've been running it for a while and am very happy with the battery life.
Like others have said, battery life while using it would most likely be helped by adjusting the display brightness, kernel settings and/or stopping "rogue" apps. You can see the kernel settings by going into the Settings Menu, then Cyanogenmod Settings then Performance. I use the InteractiveX governor (I believe "Performance" is the one that keeps the CPU ramped up constantly) with the highest overclock.
Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)
Screen brightness: Auto
I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.
Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though
If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.
Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%
Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time
A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.
Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.
An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.
I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.
Hello and thanks for reading ,
I am experiencing a very bad tablet battery life since November 2013.In these past month's i have visited forums, flash factory OS,turned off the radio(and wifi), installed many battery saving apps (didn't work), boot safe mode(drain still there), rubbed snake oil(really dangerous) and the battery still drains faster than a monsoon gutter.
Below is a screen shot of the tablet after I left it to idle for one night .

I've got exactly the same problem; battery drains very quick even with airplane mode on. Tablet Idle is the culprit according to the power settings. I wonder what this means and how to solve this issue. can hardly use the tablet, i always need to recharge it.

Same here, and this just started a couple of days ago. Usually, with my usage pattern, I only needed to recharge once a week. Just over night this changed to nightly... Quite annoying.

Registering only to add my "me too" to this problem. The battery is depleted in a few hours (6 to 10) when the tablet is turned off, no sleeping, turned off, even after using the recovery menu option in order to force the power down. It is always lightly hot to the touch when it is automatically discharging, again when turned off.
This is my first Asus device and I am trying to request a refund, I don't want a new device, or a repaired one. I want my money back. I am not sure this will happen because it was bought on December, but this is not tolerable
5 Months in and various updates later (KK 4.4.4 KTU84P right now).
The battery still drain away @ 5.0 per hour minimum.
As per original post, I have still not been able to find the source of the drain.
wakelock detector, better battery stats and battery doctor have been of little help this past months.
Assuming it is not software related, what are the chances it is the hardware ie the battery itself being the culprit.
if so i think i'll wait for the rumored 8" nexus tablet.
Guys, I am getting terrible battery life on the newest BajaRom. I was getting decent battery life but somehow everything changed. I want to note that I cannot access the Media Battery Drain Fix in the BajaROM settings as it crashes EVERYTIME i open it. I have tried everything to install something that will fix media battery drain but I am unsure if this is what is really causing my battery drain. Please any help would greatly be appreciated!

Wakelock Detector and Greenify... are ur best friends on the Note 3.
Turnoff wifi,bluetooth,gps,etc when not in use. Set CPU to on demand. I always have power saver on unless I want to run a game... doesn't seem to effect anything else.
There are a ton of tips for Note 3 battery life...just search here...
I also use LUX for screen brightness, that made a big difference also. Change you wallpapers to darker colors... mine are some sort of black background...
I can make through the day with reasonable usage on Hyperdrive RLS8 and still have battery left...
Haven't tried BajaROM yet...

Thank you for your response. I have greenify'd most of my daily apps and I use wake lock detector and still cant find out the culprit here. It says that my SCREEN is taking up 30% of my battery life after just 2 hours unplugged and minimal use and I'm down to 82%. Can my phone just be inherently defective????
This DOESNT feel right. I NEVER had any complaints of battery with my NOTE 2

Check your data usage. I had the similar situation, saw nothing in the battery usage area....but then checked data usage. I had over 2 Gigs of data usage from EMAIL in only 2 weeks! I had been using the std email app...and get maybe 10 emails a day. Obviously something goofy going on in the sync. Yet battery usage showed next to nothing for the sync process or email app.
I removed my accounts from the email package, froze the email package and installed AquaMail and my battery usage cut by at least half....my data use flatlined.
Obviously it takes power to use the radio for a Gig a week of data....but that does NOT seem to show in battery usage.
so check your data usage...see if email is way out in front. That may be your problem.

I had the same issue with battery life after I flashed to and of the KK roms. My problem was Greenify, and I don't know why. Removing it didn't solve my problem so I'd restart from the beginning. My drain is less than 1% per hour idle without it and almost 10% per hour running all the same apps with greenify in different settings. Jasmine ROM just drained for me all the time.
*first post, be nice. I only joined because of all the trouble I went through to get my battery life back.
Hello,
I find the OPT's battery life to be pretty disappointing, and a bit inconsistent over time.
I rooted and installed Amplify with some pretty aggressive settings. I have also tried Powernap, but disabled it when I saw it had very little impact.
Below are today's stats for my battery, which is just about 20% after 13 hours of moderate use.
It looks to me like wakelock should be under control (1% of battery in GSAM), but why is the phone awake so often then? Plus there was some odd GPS behavior: what is your opinion on this?
I hope I am not breaking any rules. Any suggestions would be much appreciated.
Thanks!

You're not reading the GSam stats properly, your wakelocks are almost equal to your screen time, and like 28% of your screen off time.. Not good. Your awake time percentage is roughly three times what mine is. You may have a kernel wakelock rather than apps causing problems but can't tell without wakelock detector or similar.

Thanks, will try wakelock detector and report back
Can't confirm your disappointment...
In my opinion it's OK to have roundabout 2,5h DOT and last half battery with an Lollipop rom
Wow, wakelock detector revealed a massive drain from the fingerprint scanner... Probably due to the fact that I keep the phone in my pocket with no case, so it turns on very frequently only to "read" my thigh through the fabric.
I tried disabling fingerprint scanner and had immediate benefits on standby time. I wonder if this means I will be unable to ever use this great feature, or if sensitivity will be adjusted in future OTAs.
Screen on time remains rather poor though, or at least a far cry from the 5 hours everyone else seems to get.
My battery with screen off goes down 52% after 2 days. Have 2.1, latest custom kernel,greenify + amplify. the culprit is mobile standby as there are parts of house with bad reception. airplane mode not an option
Last night I tested battery drainage overnight from around 11pm to 7am.
I lost 3% total.
I set the phone to LTE (WiFi off) and disabled Auto-Sync Data under Accounts.
3% overnight is not bad IMHO.
Hi guys,
The standby time on OPT is very bad, however if I use it I get amazing SOT.
I am gettng these 2 kernel wakelocks in OPT, qpnp_fg_memaccess & qpnp_fg_update_sram.
These are always in top 3 wakelocks. I tried to search about them but could not find anything.
Can anyone tell me what are these and why do they occur and how can i avoid them?

So ... why don't you keep it somewhere else? Or put it in a flip case? That would be an easy remedy without sacrificing usability too much. I never really get it why people deliberately expose their thighs and possibly also their reproductive organs to so much radio waves ... or keep their mobile connection activated over night ...
Actually I have solved this by always pocketing the phone with the screen facing away
I am using Sky dragon ROM and Boeflla v18
Used 70 % battery in 23 hours with around 6 Hrs active. so it is good. Mostly Used in real racing 3 and asphalt. Plus I am running several xposed mods and Layers Themes
