Serious Battery Issues - HD2 Android Q&A, Help & Troubleshooting and Genera

I have a dft desire nand running with magldr. Im having serious battery drainage. I let it die. Charged it. Let it die again and then charged it again. Even then the battery life is only around 3 hours and its down to 5%. I use it but the only things I use is facebook, xda and aim.
Any suggestions?

1. Try other builds.
2. How old odd your battery? Genuine?
3. Search and read up on this topic.

I decided to try setcpu. Which I downloaded here. Its helping some. Its been about an hour and its gone down like 5%. So thats atleast a little better. Im gonna mess with the settings and find something I like. Im do some more research too.

Have you tried turning off
Settings>Display>Auto-Rotate,Autobrightness
Settings>Location&Security>Use Wireless Network and Use GPS satellites
Settings>Accounts&Sync settings>Background Data and Auto-Sync
Settings>Mobile Networks> Data Enabled and instead of having 3G on set it for 2G
When I do this I can get a whole days use out of my phone and only turn them on when needed. Try that out and see if it helps bro

I didnt realize some of those were still on. I was pretty sure I shut almost all of those off but your post made me go check. Haha. Guess not. Thanks man.

Try other builds or you can also install Current Widget from market and view your mA useage, enable log and then you can keep an eye on it and see what the minimum useage is. It should be around 1-5 in standby, if not then you have something running that is eating up battery.
If it is at 1-5 mA and you still have battery drain then it could be your battery on the fritz.
Problem is that allot of people tend to stick them on charge before they are drained properly or also do not let it charge fully. Some battery type's have a sort of memory and if you dont charge/discharge properly it can affrect overall battery life.
There is MANY thrteads on battery issues but really this shouldnt be an issue anymore as majority of ropms have great battery life. Also remember that Android is a battery hog even on native devices.
So check out some threads and try some solutions.

Please don't let your battery discharge completely. If it does you will ruin the battery.

I don't doubt that at all after a 'few times'.
However, since I can't be arsed typing out my own explanation, how about I paste you one from the experts.
"Avoid completely discharging lithium-ion batteries
If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery.
Also, for safety reasons, do not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several months."
Also:
"Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it’s better for the battery to use partial-discharge cycles.
There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device’s power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated."
So as long as you were hitting the 30-charge-and-dump schedule, you'll be ok.

Proper way of calibrating battery?

Hi folks, I'm running CM6 8/26 nightly with Snap v7.4 kernel with SetCPU set to conservative on 998mhz max and 245mhz min. I'm getting horrid battery life and I think I'm doing something wrong: I wiped battery stats in Clockwork and now my battery SUCKS. -.-
Question is, what its the proper way of calibrating an Evo battery? I've seen the official HTC response but I don't think it's going to make a difference. Isn't there another method that requires you to drain the battery? Any info will be appreciated I've been looking at forums all day.

You can't just wipe battery stats - there's a process to go through. What you're referring to is Cyanogen's battery recalibration method found here. Read through fully before wiping anything.
Thank u very much, I wiped the stats by mistake

Actually it is almost as simple as wiping battery stats. That command he gives is what the wipe battery stats command in the recoveries do.
1. Charge battery to full (where it's actually 100% not green light.
2. Boot into recovery wipe battery stats.
3. Fully boot into os then unplug charger.
4. Leave unplugged until the phone shuts itself off.
At that point you should be calibrated.
On a related topic, the Battery Graph app available in the market also has an option to wipe battery stats from within the OS, doesn't it? Might save having to reboot into recovery once you're charged up.
It's a lithium battery. You can't condition it. Just use it as normal and ignore all these placebo effect steps.

They're not calibrating the battery. they're calibrating the phone to know when the battery is really fully charged which, until you do this, is not the case when the charge light turns green.
Regardless, none of this worked. I've quit all services, no sync, auto brightness and wifi and I'm still getting horrible battery life. SetCPU is set to conservative. It's BULL**** my display is on for thirty minutes and the battery dies 20%. I played a game on my friend's iPhone 4 for twenty minutes and his battery barely died 3%. This is really unacceptable and I'm probably going to return my Evo or sell it if the battery life doesn't get better soon from these methods I'm seeing online

Crazy man, maybe something happened cause that is pretty bad.
Have a backup to go back to, prior to this happening, to see if it reverts back to normal?
Naw nothing happened to my phone...... All of us Evo owners should be able to use this beautiful phone with all of the features at max without the battery going to ****. My phone has behaved this way since unboxing. I'm not a big fan of the iPhone 4 but I will give it props on battery life. I have yet to try the longer HTC method but it seems kind of pointless.....
Sent from my PC36100 using XDA App
If it has always been like that then you may have a bad battery, if it started after you wiped the battery data then it is just showing you bad readings.
You should be able to get a good calibration if you reset your battery data again, maybe try through your recovery if possible, and then fully charge it with your phone turned off. Once it is charged you can either use it normally till it dies or you can tether, use gps, watch youtube, etc, and drain the battery down. Just make sure you go from a full charge to the phone shutting itself off without plugging it in to anything. Do that charging with it off and using it till it dies two or three times and your battery stats will be calibrated.
When I did this to mine it showed my battery at 0% for at least half an hour before it finally died, and that was with me listening to pandora and browsing the web.
Edit: FYI, the Evo's talk time is usually between 6.5 to 7.5 hrs, the iPhone 4 is around 7 hours also. If your battery is not lasting that long you need to take it in to sprint and have them give you a new battery.

HTC's method worked wonders for me. i'm a heavy heavy HEAVY user (no, not fat) and I get a good 10 hours with everything besides 4g on plus surfing, gaming and tethering for SEVERAL hours. For all that I do on my EVO 10 hours is HUGE. If I have a moderate day of usage (maybe a little more than moderate for the average user) I get around 19 hours.
Btw none of this will help if you are getting near 100% awake time. If that's the case you need to find the software causing that first.

Try this, it helped me. I did not come up with this btw.
With phone on, charge until green.
Unplug and turn phone completely off.
Charge phone until green once again.
Unplugand turn on. Once phone had turned completely on turn the phone back off again.
Charge until green one more time then unplug and turn on and you're done!

what u mean i m doing it wrong
To be fair, running a smartphone without e-mail synced would sort of defeat the purpose (for many). Though to the point of this "official" thread -- I'm thankfully happy with the battery life on my Vibrant, and I have Gmail, Twitter, etc. running.
Let me guess you don't drain your phones battery either during its first use and let it completely charge up (while off) to 100%.
I did this with my wifes and mine. This has been the best battery life I've had out of a smart phone to date. I've gone up to 36 hours on one full charge. However normal is 18 hours then I charge when I go to bed and I don't even have the warning that my battery is dying.
I hate restarting my phone, it always resets my battery stats. I love seeing how long I can go .
I'm glad we have an official thread now.

I've read that this isn't necessary with Li-ion batteries (and in fact completely draining can be bad, though phones have a built-in protection mechanism to prevent total discharge)?
I will add that I briefly owned a Nexus One, and find the Vibrant's battery life to be much better... but "YMMV," i guess
completely draining IS bad, but our phone cuts off before this should be an issue (hence why, even if dead, you can still cut your phone on... though for not very long, this is not advised).
That said, the Vibrant has had VERY good battery life for me.... I also think the OP is "doing it wrong."
Seriously. How much do you do on the phone. The only way I drain this thing is surfing and downloading. I dont really have a lot of widgets. I guess if ur running alot of stuff you'll be burning battery life

Changed battery, changed device, changed ROMS. Only two things I see in common, the Vibrant and you. Personally I haven't had any issues with the Vibrant.
Just checked my battery status.
70%, unplugged for 8h 7m 38s
Display - 25%
Mediaserver - 24%
Cell Standby - 23%
CPU usage for Mediaserver - 1h 15m
Approx 1 hour of music and 5 podcasts.
Applications that I'm running that sync:
Facebook
Gmail
Google Voice
Google Talk (usually intercepts the first message then focus switches to my Desktop client)
Email via personal IMAP server (synced every 30minutes)
Yahoo Fantasy Football App
Mint App
bought the phone last week, charged to 100% with the phone off then began using it non-stop. the battery wasn't that great at first, but i have since gone through about 2-3 full cycle charges, usually draining the phone until shutoff, then leaving it on USB charge overnight. charged to 100% by the morning, then i would turn the phone on and charge a bit more until it read 100% while on. since then i have charged a couple times with the phone on, here and there. my last charge was with the phone off, wall charged overnight. no top off needed.
all syncing and background data turned on
use wifi at work, set to never turn off
3g disabled unless i need it
auto brightness
settings > sound and display > DISABLE "power saving mode"
use black.png background because i like how dark it is
don't use any data grabbing widgets
it's been 32+ hours since i last unplugged and i'm sitting at 22%
two full days use off a single charge is a-okay in my book! other peoples' use may vary, but this is my personal setup. i think doing a couple of full cycle charges in the beginning really helps. i'm completely satisfied with my current battery life, even with all the speed tests, wifi/3g surfing, and goofing around with the GPS

Unique Battery problem

Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.
Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App
Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.
So where is the "unique" problem?

Battery Charging question

Hello all, I would like to know what % to start charging my phone is better to the battery? it's draining so much and there is no extra battery for sell in my country yet.
I did search many posts and all answers are different. I am so serious only this and I hope I can have a better way to keep my battery longer... thanks for your attention.
it's usually not good to let the battery totally discharge. So charge it before it completely dies.
oh really... but I already made my Note battery to 0% and shut off itself two times I also did charge on 40-50% to 100% bcoz I know I would have to stay outside without battery charge after. I wish I can get an extra battery in my country soon.
Your problem is probably not related to the battery but to some apparently draining all the juice. There is an app called something like betterbatterystats, not sure on the spelling though, it might help you to find those draining apps. It's been reported manytimes here in XDA.
And for your information it's better to charge when the battery dies for the first couples of times. I don't think that it makes a big difference after that.

U may also want to check the process or apps running on the background?
I freezes all the unwanted apps or process les one by one to try it. But in terms of the batt usage, I believe if u don't use it much often u can still stand by for at least a day. Mine running on full 3G, but screen brightness set to lowest and STILL facing some batt drain issue.

Charging from a total 0 is actually good and most technical people will suggest the same. In fact a full battery drain every month and then a full charge ensures your battery gets a full charge and a complete battery rotation. This is a good thing that you did and let no one tell you otherwise.
However, for normal usage the lower the better at which point you charge is best.
All of these batteries comes with xx full cycle charges - meaning how many times they will last from 0 to 100% before they degrade and start giving less efficiency (around 85% on future charges) after the full cycle charges are over.
You may want to use 10% as a good benchmark to ensure you dont lose an important call with your phone off. The battery saving mode on the Note will also help you reduce loads at times and improve battery life (at cost of system power).
Congratulations on using the Galaxy Note, which I feel is the best all in one device in the market!

I second this.. its funny how still people still believe those myths about batteries (like charge 100% before you use the device first time).. those issues are easy 5-10 years old.. batteries now a days a have smart chips built into them that can control the battery health
So, I can charge my battery anytime when needed?
Also, for screen brightness, i set auto brightness is better than setting it manually low?

ICS Upgrade gives you a shorter battery life ??? Read how to get long battery life

Hello friends,
Here finally I upgraded to ICS and honestly I get great ( huge ) battery life..
before also I get upgrade and i get very low battery life because of low calibration of battery without my knowledge..
so I've reverted back to gingerbread 2.3.5 and I'm happy
But who wants older version when the new shiny and superb upgrade of ICS is there anyone ???
So finally I upgraded to ICS and after many searching ,, finding ,,, reading and confusion with doubt The great battery life will be came out from our Loving SGN.. so please do not get disappointed just see below.
Really here I provide you some small and very easy steps by using it you will be definitely be happy with your ICS upgrade ..
you doesn't have to go anywhere and doesn't have to buy anything with your valuable money ..
Really happy
Then read it and get longer and more juice from your battery..
you have to follow some easy steps below
1 . First upgrade your ICS from any source whichever you like ... by kies air or Kies on PC or mobile odin or Via PC ODIN [ please do full charge of battery before any upgrade low battery can make your phone unusable or dead you can get more info on other threads ]
2 . Hope you have upgraded successfully.. then use your phone till your battery goes down to 5 % or below...
[ Caution ] Do not use it till it switched off automatically.
3 . Plug your charger and charge it till morning if you are charging at night or else charge it around 6 to 7 Hours even after full charged .. it's important step.. Do not Ignore it ..
4 . and then use it as per your requirements till battery shows 5% or below
5 . Repeat the step 3
6 . Do it around 8 or more charging cycles.
You get really miracle after 3 or 4 full cycles...
[ caution ] do not overcharge after that i.e just do 6 to 7 hours charging for around 5 - 6 cycles ... after that charge till battery shows full charge i.e around 3 - 4 hours. do not overcharge ..
made it habit of full charge cycles if you are comfortable with it. it really gives great battery life then average battery life.
Hope It'll be helpful to you
Regards
It is better to charge randomly than doing full charges every time on Li-Ion batteries.
Doing full charges every time on Li-Ion will result in battery being end-of-life faster...
Overcharging is also bull****. The phone automatically stops charging the battery when it's fully charged.

As per research the full cycles of Li-on battery gives good hold of charge and also batter life..
in all honesty your post is as useless as mine right now.
According to me, It can be considered as myth . . If the battery needed to be calibrated then it must have been official.. n 2ndly the procedure above is not professional at all... So dnt even think it wud work.... Neways someone can always try and authenticate...:thumbup:

Doing full charges for calibrating the battery: no problem if you do it once in a while
But you are suggesting people to ALWAYS do full charges on their Li-Ion battery...
8-10 cycles after eachother is too much as well. 2 charges will be enough.
thanks for more info bro
maybe 2 is enough but in many cases it'll be not...
Why do you need to do this just because the OS has changed? And if so then why is it not require on GB?

I totally agree with you!
Also, never let a battery dry for long periods, it will be damaged beyond repair.
Lithium Ion batteries perform better when you keep it as charged as possible.
I call this thread BS too... But I thank the user for the effort
Yeah ICS battery life sucks. I've done what OP said and I still get 4 hours less Battery life than what gingerbread would give me.

It's essential because all the states of your battery will be wiped in most of the cases while you upgrade also it's helpful to you if you upgrade your ROM.

ok bro try this procedure and also report us..
In most of cases we have solved this issue with this procedure even i had this issue before now it works like a charm.
I did several full drain and full charge cycles when I upgraded to ICS. Still got the battery drain bug so I think its more luck than anything else if your battery lasts.
In my case I've discovered that power cycling the device after charging is the most reliable approach.
Install CPU Spy, run it after a charge, reset the timers, and then leave your phone in standby (screen off) for 30s or so. Unlock the phone again, and check CPU Spy - if the 'Deep Sleep' cycle is unused then do a phone restart. This has worked EVERY time for both me and a friend who I told about it. I'm getting similar battery performance to when I was running GB!
Battery life depends on a lot of things, ROM version is not the main thing.
This is my setup:
ICS version LQ3
Speedmod 3-3 Kernel
Disabled a lot of Samsung stuff (Readers hub, social hub...)
No automatic sync of twitter, e-mail, etc
I get pretty much zero battery drain when in deep sleep mode.
Of course when using the phone, screen on, Wifi On, autobrightness... battery usage is bigger and you can drain the battery in only 4 hours if you go for it.
Be careful with:
- Live wallpapers, I've seen cases where they remain active all the time
- Apps syncing data on background every few minutes (facebook, twitter, etc)
- Apps uploading a lot of data on background (google+, dropbox..)
- Games that crash and leave the CPU in a high power state until you reboot
Agree

I am agree with this reply.
If you want to get best battery back-up;
Disable all apps which are working in background, sync n update really eat the phone battery.
I am using my note with active mobile network or wi-fi for a whole day and playing games too without doing this F**KING trick.
The only way battery life gets sucked of Galaxy note is if it doesn't go into deep sleep when not in use.
To all those reporting low battery life: How much battery do you end up losing overnight. ( approx 6-8 hrs)
I typically lose <5 % ( best case scenario has been 1 %)
I had a problem last week and lost 30% overnight and found that it deep go into deep sleep.
and the best solution i found in another thread was to unlock the phone before unplugging from charger
Simply try it: For me normal time between charges is 36 hrs ( battery is near 25% level)

Battery Lifecycles are connected with the phases of the moon. So you'll get the most out of your battery if you dance at midnight when having full moon spitting five times on your battery.
Many people are of the myth of overcharging n recharging, but its not true wIth lithium batteries, phone will automatically stop charging, if only anything helps its battery calibration,u can do this with a free app called battery calibration, time for the tread to be regarded as close, still useful for noobs

I get great battery life my phone lasts for months on end without dying. I just plug in the charger every night and my battery has not died yet.
