Need better Battery life!!! help!!

hey im using leedroid v1.3 and the battery life on my phone is horrendous, i left the house at 11am this morning with 98 percent and after a 10 minute phone call i had 75 percent battery by 12 oclock. do you guys have any tips or things i can flash to get the phone through a day and a half or even 2 days somehow?
also having an issue with the speakerphone, its the lowest volume of any phone i think ive ever owned, ive got to put the phone to my head, so its basically like making a call but using the back as an earpiece. thanks for the help.

I'm having the same problem with my phone, on any rom. According to CurrentWidget, the Ma being used by my phone will not drop below 150, even while idling. I'm starting to believe that my battery is faulty.

Are u guys calibrating the battety?

I thought I was, but apparently I'm not. Can you point me in the right direction?

Download the battery calibration app from the market. Charge to full run the app calibrate.....drain than calibrate again and you should be fine.

Upgraded to v2 and ran the battery calibrator. Phone finally lasts a day. Thanks. Am I supposed to run the calibrator at like 10% or should I let it die and run it after a 100% charge?

Battery calibration + managing screen brightness massively increases battery life. You need root to be able to clear battery stats, right?

I believe the calibration tools want you to use them at 100% charge. I got a chichitec 1900mA/Hr battery, calibrated (i guess it is now) and my phone went for more than 24 hours before hitting the 49% mark. This was with light use (checking email, checking web forums, playing some Angry Birds, and making some phone calls) but still a HUGE difference from the stock battery. Also, I turn off data connection via quick settings when I am at home. I do turn on wifi though while at home. Calibration ought to help out big time, as these phones are reporting a dead battery long before it is really dead.
Also, dont pay attention to the current battery monitor's report for standby current. It isnt accurate.

That's the one reason I keep going back to the stock setup I just seem to get better battery life out of is than any of the custom ones I've tried. I've only tried a couple. Has anyone found a ROM that gets better battery life than stock?

Frequent shutdown and battery drain

Im having problems with my phone battery drain and shutdown. I tried 3 different roms and they all had the same problem. Im assuming it's not the rom. Tried insertcoin sense4, coindroid, and now leedroid sense 3.6. Please help me, i had my phone plugged off for 1hr and it already drained half of my battery. It seems like the phone shuts down because of low battery even though it still has because it dsnt shut down when plugged. When i turn on the phone, it will shut down again unless i turned it on plugged. Please help me... Maybe its the firmware. I rly dnt know. All i know is flash stuffs

Sense ROMS Drain up A LOT of battery :l Perhaps try reflashing a ROM, I would suggest Virtuous Inquisition, and CALIBRATE the battery ( Let it charge overnight ), If your battery still seems to be draining to half a bar per hour after a full charge, try changing your battery~

Okay I'll try that. I'll also check if it has something to do with overclocking

Definitely, overclocking takes up more battery and can damage your processor .

Actually overclocking to 1.7ghz gve me much batter battery using miui but sense roms USUALLY take up a lot of battery but they are pretty much there now eg arhd or coindroid, when you flash a rom drain the battery to <10% and then charger it up fully and you should notice brttery battery.
As for your shutdowns, unless you are overclocking to above 1.8ghz your phone shouldn't shutdown, your battery has most probably just worn out, either order a new extended one or try taking it out for the night and then put it back in, should work then.

Same thing happens to my phone from time to time. In my case it helps if I remove the battery and then press and hold the power button for 15 seconds, then put the battery and cover on and do a full charge without turning the phone on.
You could also check to see if the battery is firmly seated in its bay and if not, wedge something in the gap to keep it firm against the contacts. There is a quite popular thread about it somewhere on this forum.

Use battery calibrator fron Play. Run it 100% and press "calibrate" in the app. Can also wipe battery stats as well.

Who is it made by I see a lot of results when I search that.

Any of them will do. They all delete the same file to calibrate.
Once you calbrate, let the battery dtain all the way to power off for the first cycle.
Also, its not unusual for the battery percentage to jump alot on reboot. It will drop down ro the correct amount pretty quickly.

It could be the first signs of a dying battery as well.

You do not need to drain your battery completely down (until the phone powers off) to get an accurate calibration. Anything below about 15% will be good enough.
Although it is rare, letting a li-ion battery drain completely to zero can sometimes cause it to fail. There are sensors in these batteries that makes sure that they don't ever drain completely (even when we see zero, there is still some power left - similar to when your car gas light comes on but you still have a few gallons of 'reserve fuel) Sometimes these sensors can fail. If that happens, you have a bad battery.
Also, after calibrating give it a few full cycles to gain top accuracy. The jump you see after a reboot is normal, though it shouldn't be as severe as you mentioned.

Hi my friend,
Some say "battery calibration" app works some says it doesn't, don't really know but "wipe battery datas" in recovery does the same.
this happens when you flash different roms and some roms does not include battery calibration scrips. My rom does and i never have this issue, works very well.
this issue resolves by itself when wiping data and giving it 2 or 3 complete cycles.
Be patient then , all will comme back to normal.
I also saw a new app called "battery repair", i just bought it on market, but can not tell the results now because too early. i took it because it repair yes but most of all give you more time of use ...
cheers

Randomly turns off

Hello,
My htc sensation randomly turns off.
The first press of the power button causes the screen to light up a bit then turn off. Then I have to press and hold the power button to turn it on.
This started happening recently. It happens randomly.
At first I thought it had something to do with my current ROM, so I changed it, but it still keeps happening.
Any advice?
Thanks

More information needed, What rom are you using now, what kernel are you using now - sounds to me like a kernel problem

This happens to me too. It started when I upgraded from GB to ICS (Stock Sense 3.5 ROM to Virtuous Quattro). It is really annoying because it happens often if I want to accept a call.
What I did was to completely wipe my phone with 4ext, formated SD Card and formated the phone filesystem to ext4 in 4ext recovery. Then it did not happen for 5 days. Now it starts again. I hope its not a hardwaremalfunction or issue.
ROMs I tried but it still happened:
- Virtuous Quattro
- Virtuous Inquisition
- OpenSensation
- MIUI AOSP from blackwing
- OrDroid 8.1
Maybe I should try the new firmware 3.33 or reflash 3.32 or flash 3.32R2
The strange thing is you cant really recreate it. It happens too unregular.

reflashing firmware sometimes solves the issue
either you can reflash your firmware or ..try an updated firmware

I just flashed 3.33 Universal in. Lets see what it will change

I have a similar problem but not sure what it is. My sensation will charge to a full 100% and once it lowers under 70% it will shut off. When I turn it back on the battery will be some outrageous percentage like 5% or 14%. It immediately dies after every turn on never actually reaches 1%. I've fully wiped flashed several roms so its not software I think. Maybe I need a new battery? Any opinions ?

Perhaps worth a try:
Insert a little piece of paper between the top of the battery and the phone. This will push the battery against the pins and has been known to solve all kinds of silly battery problems.

i read it on a thread here in xda and its worked for me...my phone used to switch off randomly while in my pocket..its a battery issue..remove the back cover and push the battery down..you will notice that there is room for it to go further down..just wedge a piece of visiting card in the gap and see if it works for you..it has for me..

I would definitely purchase a new battery. Get a long lasting battery like Anker. I really love my Anker battery its made a huge difference for me! I'd do it soon! Before the battery dies completely! Best of luck hope this helped.

Phone shuts off at 6%

Hi everyone,
I'm currently running CM10 on my AT&T One X. It runs great, but when I hit 6% battery, it suddenly jumps to 1% and shuts off a few seconds later. I've tried recalibrating by using the app available on Google Play, as well as letting it shut off and recharging all the way. Neither have seemed to fix the issue. My question is; are there any other ways to recalibrate the battery, or simply cause the battery indicator to display the proper percentage?
Thanks to anyone with advice!

Have you looked to see if anyone else on CM10 reporting anything similar?
In any case, the battery meter is not all that accurate in the best of conditions. I wouldn't trust the meter being below 10% to mean you have much significant battery. Really, by the time you hit 20% or so, you should be looking to charge.

Why you letting it get that low? Normally around 10% I plug in.

It's not habitual or anything. I just normally don't plug it in until I go to sleep, and sometimes it dies before that time comes.

This isn't based on facts but my 2 cents is that because the calibration of the battery isn't wiped, it's not accurate. There's no wipe battery stats in TwRP. If you ever notice the battery percentage in TWRP after flashing many ROM, it differs from the actual phone.
I wipe the batterystats.bin in data/system when full then reboot but who knows if that even works. I had my phone turn off @ 3% once so who knows but charge it as soon as it gets in the teens. Its bad for the battery if it keeps powering off when low.

You're right: that isn't based on facts.
Battery stats get reset every time you charge your phone. Manually wiping them does nothing.

This issue has been discussed in other threads. Seems to be specific To CM roms only.
Some report steep declines from 40% to zero in seconds. You seem lucky.

I wouldn't worry about it. Mine turns off anywhere from 5 to 15%. The battery percentage is just an estimate based on the software, it's not an actual indicator. As such there are tons of variables that can affect when the phone is actually out of battery.

TWRP also doesnt report battery correctly and it has nothing to do with the stats. It is taking more of an educated guess as to where it's at. Believe it has something to do with are phones.

thanks for the info.. i have experienced this issue also

Battery percentage is guessed at based on voltage. As the battery drains, voltage decreases slightly. Yes it is an educated guess. Every battery behaves slightly differently and has a unique profile or discharge curve. Some may be steeper than others at the end, but the device should learn this and adjust accordingly. An internal short in a composite battery like this would also exhibit this behavior, only exhibiting itself at certain voltage levels(dependant on location of physical short in battery) where voltage drops to 0 at that moment. I have seen this issue in defective packs where they work fine most of the time, but then zero all of a sudden. I'm not saying this is your problem, but the case design/new soft shell battery(no hard plastic shell to protect against the internal layers from being squeezed together) is wide open to physical damage from the phone being compressed.
Try a stock ROM and verify it works normally. If not, the battery is damaged.
My One X has never shut off before it reached 1%. I unlocked it 4 days after getting it in the beginning of June and have been running CR ever since and never had a steep battery decline.
