My phone has been on for about 5 hours and it is dead. Power usage says it has been running for 16 hours. There are no apps running, the screen brightness is turned down, and I have turned off many of the sync stuff.
I turn it off every night and put on charge. It says it's fully charged in the morning. Battery life was good until just recently, maybe last week or so. Is there any way to reset the battery?
There is, but you need root access. You can either use recovery to clear the battery cache or there are a few programs that will reset it for you.

Which is the best style to calibrate my battery? I't only lasts for 10h.
10 hrs is pretty good
i only get 4 hours under heavy use
I forget which thread it was but it said to completely discharge until the phone switches off (ignore please plug in prompts) and completely charge it back up 5 times. It worked wonders on mine
4 hours? pah, i can kill mine in under an hour lol
seriously though, it all depends on usage and how much you have running on the phone (big widgets and social feeds for instance), screen brightness also has a big impact.
On average i get a day out of mine but my mums boyfriend, with the same phone uses it far less and has had 3 days from his on one charge
Ok i'll try your method. Thanks guys!
I have mine going down to 79% within half a day,only standby and frequent switching on of the screen, is it normal? Thanks!

So you mean discharge completely and recharge completely and repeat this 5 times?
What about the following method :

Just wanted to share that I got an improvement
after recalibrating the batery,
Basically just charge full with phone on
then turn off, charge, turn on, turn off, charge.
I advice this for those who have flashed the firmware..

So which one of these two methods is the right way to do it?
EDIT: And how good is this guide?
1. Run the device down until it turns itself off.
2. Turn it back on and wait for it to turn itself off again.
3. Remove the battery for 10 seconds.
4. Replace the battery, but leave the device off.
5. Charge the device until full and then for another hour.
6. Boot into recovery and reset battery stats (or, go to console and type “su” enter, followed by “rm /data/system/batterystats.bin”)
7. Run the device’s battery down until it turns itself off.
8. Charge to full while off.
9. Restart and use as normal.

IMHO, the battery stat is just pure witch doctor style..
Id recommend you use the phone till it drops down the 2% then power it off and charge it while its off.. that way it MAY take upto 4-5hrs charging when it says its full remove the battery for 1-2mins then install it again and charge it while unplugged its gonna charge for ~5mins and when its full disconnect the charger and power on the phone.. you just need to do this once ( on my experience ) and charge as often as possible since its not a good idea to keep draining lithium batteries

Do it this way:
Make the phone empty.
Charge it all night (8 hours + ).
While still charging, open applictaion: Terminal Emulator (it is available on the market for free)
Write:
su
rm /data/system/batterystats.bin
it looks like that nothing really happens, but it does.
Reboote the phone. Important!
You will see the difference. I get from 1 day before to 3 days now.
For doing this, your phone, of course, should be rooted.

There's another method^^
I really don't know which one of the 4 battery calibration methods that I've mentioned above I should use?
I've read from many sources to not worry about frequent discharging/charging of your battery. The lithium-ion batteries we have in our phone will degrade based on cycles (when a certain number of charge cycles have been reached). As for overcharging, the phone is smart enough to stop charging once the battery is at 100%. The battery will slowly discharge, and once it hits a certain point between 93-98% it will start charging again.
As for which method works the best...I'm struggling with the same issue. Personally I've tried almost every method other than the reset battery stat (which I plan to do as a last resort).
I have found that the battery gets better after a few weeks of use. The full discharging/charging does help marginally. The turning on and off method of charging also helps marginally. The biggest culprit is usually background apps preventing your phone from properly sleeping or activating your data when your phone is locked. I was using juice defender and my battery still drained crazy. I JUST changed my juice defender to turn on data for 2 mins every 30 mins (as opposed to 1 every 15) and it seems to have made my battery better. Before I did this, my phone drained 40% in 6-7 hours (while i was sleeping). Right now... my phone has been active for 5h48min and is at 72% (a bit of texting, a bit of 3g, and wifi). Here's hoping it'll get better.
This thread helped a lot
My phone drained 70% of battery from 5am till 12pm (while I was asleep). When I saw the battery usage stats it said that Android OS draind 68% of the battery. I flashed the phone on sunday. I should do a calibration then, right?
I'm going to try this method:

I think there is a problem with my 3500 mah battery from sedio. I have had it for a few months now and it really wasnt what i expected. I had heard people who have had 2-3 days + battery life from one charge when i cant even get 24 hours on a single charge with out playing a game or using gps. Im running sky raiders 3.5 right now.
Is that bad? Should i try and get in contact with sedio? Any other tips.
Thanks in advance!
EDIT:
For example today:
13hrs since unplugged. 29%
awake 4.5 hours
That sucks right?

That is pretty bad. I'm at 12 hrs 50 mins since unplugged, 3 hrs 15 mins screen on, on stock battery. What kernel do you have?
Sent from my Droid Incredible running CM7 RC2.
I have to admit i am pretty new to all this stuff, just a couple of months in so i wouldnt know how to change my kernal but im sure i could figure it out if i had to.
Heres what i got:
There are all kinds of things you can do to extend your battery life but by far the simplest is to turn your screen down to quarter brightness and turn off the auto adjustment.
You need to reset your battery.
Step 1
charge the phone while turned off till the light turns green. Unplug but do not turn on then after about twenty or so seconds plug it back in and the light will be Orange again wait till its green.
Step 2
Once the charge light is green for a second time boot the phone into cwm and clear battery status. Make sure phone is still plugged in
Step 3
After you clear the batter status reboot the phone making sure that you do not unplug it . as soon as you're able to open up your app drawer once the phone has rebooted then unplug it.
Step 4
Do not charge your phone again until the battery dies and the phone shuts off.
After this you are done

For the longest time I was convinced the eBay-generic 3500mAH that came with the phone when I bought it online was faulty because it seemed I was getting identical results from my stock battery even after wiping battery stats. But now after running the battery for a week or so continuously and not swapping out to the stock battery it seems to yield much better life now that I calibrated the phone to this battery and left it in for a while.
So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.
If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.
I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.

I baught this phone 3 days ago and it the battery is a big problem and I really don't know why
For example I left it at 83% downloading some updates with WiFi and I came back after 40 minutesto find it at 76% and from the battery setting the cell standby (when I open it it says something about cell radio) used 74% of the battery and after those 40 minutes it became 77%
I would appreciate any help from u guys.

So you've lost 7% in 40 min while the phone was downloading updates. Nothing abnormal imo.

When screen was off during the night it hasn't dropped at all, and when I use it it drops 1% every 2-3 minutes with everything off except for WiFi
With the lowest brightness

1% every 3 minutes = 5 hours of screen on time.
Again, nothing abnormal here.

Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.

My Alcatel Idol 4S Windows 10 seems to lose charge. Yesterday, after fully charging around 4:00 PM, I let the phone sit, completely unused, till this morning. It was turned off with LTE enabled...nothing else on, and most everything set not to run in background. I also have set the phone not to sync automatically. Now at 9:00 it is at 94%. When I browse or use YouTube it really drains quickly. I have done a factory reset. Any thoughts?
Once the phone went down to 10% and powered down. Afterwards it charged normally. Any thoughts? Thanks.
Update: A 20 minute call drained the phone by 4%
Update 2 I went back in and made sure that absolutely nothing is working in background. I wish another Windows owner could give me a sense of what kind of battery usage/drainage is normal for this phone. I amcoming from a Lumia 521 which drains slowly. I'm reluctant to return this to T-Mobile and wind up with a refurb.

Last night I charged the phone to 100%, turned everything off...phone in airplane mode, so no cellular drain. This morning phone at 95% with nothing running and nothing in background. Surely someone on this forum must have insight into this.

5% battery drain overnight seems about par for the course, no? Means your phone untouched would stay on for 6.6 days in standby mode if my math is right.

is that par for the course? Some people seem to lose no or 1% charge when in standby overnight (everything off). How much charge do you lose when you make a 20 minute call, or play a youtube, or when your phone is not in use, but is connected to cellular with bluetooth on?
Thanks for your response
Send it to Alcatel for a battery replacement. You will get the same phone back that you sent in. I just did, and my battery life issues are much better.
The simple fact that your phone shuts of at 10% means that you need a new battery. It will get worse.
