Battery Life APP

does anyone know of an app or widget to say how much *time*, not percentage, is left on the battery?

If you are on Android, try Battery Doctor.
It gives all vivid details pertaining to your batter state.

Do any of these really work?
I would LOVE to have an app to increase the battery life on my TBolt, but from what I hear, none of them really work without turning off a lot of the features of the phone. You might as well turn the phone off to save battery.
I'm using one of the kernels from Adrenalyn which is helping tremendously, but wouldn't mind even b etter battery life

horrible battery life

hi all i use a w8 and my battery life is just awful
sbout 1% every 30secs on use and 1% every 45 mins on standby ...it just sucks
- i use GDX rom
-rooted
-stock kernel
-use 360 launcher
thats it
my battery seems to be buggy cause sometimes it shows 64% and iwhen i restart it shows 67% ...any help?

I've read battery life has some to do with the rom and I just saw a post that says after flashing a from to wipe battery stats in recovery I'm looking that up now also I don't think a battery saving app would hurt I use juice defender but I'm a noob Im only telling you what I read so look into it to make sure

I use juice defender too. I found that it helps a lot - doesn't matter if it was rooted or not, battery life improved a lot with the app.

hmm kay i think i will try defender ..but srlsly i dun get why it drains so fast ..i tried with 3 other roms but with no good

Try these steps below.
Lower down your Brightness
Set your Phone to Power Saving Mode
Turn off your Wifi when your not using it.
Download Power Saver App: Easy Battery Saver + Task Killer.

ermmmy phone don't have power save mode...it;s a rather old model ..and i never NEVER on wifi , bluetooth , 3G ,data , sync etc ...and i put brightness to lowest ( to save battery since i am in a crisis )

ok so i install juice defender ...and something weird is going on ...my battery never moves ..which is goo and wird .it's stuck at 7f 2or a hour s i restarted and it's at 65% for 2 hrs now is this a bug or is my phoe's battery life is insane?

Ya i use juice defender on extream then just ad the apps i want data and wifi for then i use white killer a root app killer and it frees up half my ram from crapware now all i need to get is titanium pro to freeze my crap ware after doing this my optimus thrill trill has probly 3 times the battery life and if your fermilure with this modle it really sucks juice. Alot better now.

This post contains the news that wiping the battery stats has zero effect.

still...my battery life is SHIIII

You mentioned your phone is an older model; the issue might be that your battery is wearing out. After so many cycles of charges/discharges they lose capacity. You might want to look for a low cost replacement battery if the mods you're trying for your phone aren't helping.

nono ..w8 is released at may 2011 i bought my phone last month ( it was flawed ) so lst week the retailer gave me a new phone and this issue happen

[Q] High battery drain (50-100 mA in current widget in sleep)

I have an unlocked T-Mobile Sensation 4G and I've tried a lot of different rom (with Sense and AOSP, GB and ICS).
I had made battery calibration every rom change (Full charge -> wipe battery stats -> do some full discharge/charge circles in normal use).
Every time I have 50-100 mA battery drain in "sleep" according to Current Widget and another battery widget (tried another to commit that Current Widget tells truth).
The phone settings are maximum power-saving:
Fixed small brightness
2g only
Data and auto-sync are turned off
Wifi only if needed
CPU is downclocked to 1.2 gHz
Battery is stock. Phone is two months old.
In my regular usage (1 hours of calls, 10 min wifi) phone dies in 12 hours after full charge.
It is not my first android and I'm not a total noob. My Desire HD with one year old battery live 2 days with my usage.
Also I notice, that sometimes battery left is not accurate and changed after reboot to a bigger value. For example, 80% left -> reboot -> 82% left.
Any suggestion?
Thanks in advance!
Sorry for my poor English...

My suggestions:
1. Use system tuner or a similar app to check up on which apps are draining the most power (keeping the CPU on, etc).
2. If no culprit can be found, full wipe and reflash your ROM, and refrain from downloading any apps, see if that improves battery drain. If it does, slowly install more apps until the battery drain goes up again, and you'll know whats causing it.
3. If reflashing does not help batter life, you might want to try another ROM or kernel.
4. If none of those help, or even if they do, I highly recommend an ANKER battery, it'll at the very least boost your battery life a few more hours.
5. If the battery life still sucks, then it might be a hardware issue and you might want to get it exchanged or whatnot.
I used to have the same high battery drain problem, but after flashing new ROMS/Kernels and switching to an ANKER Battery, I now get 2 days of light/medium use out of my Sensation.
Currently using Insert Coin 4.5.0 with 1.5GHz overclock+undervolt if you're interested in trying.

Thank you, I will try.

How much does your battery actually drain overnight? Should be around 1% per hour or less if all is well. Disregard currentwidget in deep sleep mode as the Sensation has a very broken meter.

I'll check it this night.
With jumping battery meter I don't know if these values will be correct. But when the battery value reaches 0% the phone shuts down immediately and don't turn on. So 0% it counts well.

i think im also having the same issue . i checked current usage when in sleep mode.its between 50-80

12hrs with the standard battery is actually very good for a sense build, without sense it should go around 15 - if the battery is in good condition. The battery driver for the sensation is very buggy and you won't get accurate results with any measurement app. Don't worry about the standby or inuse readings as they will both be wrong.
If you're battery drains faster than 1% per hour in standby, assuming you are in a good signal area, then use a system info app to see which program isn't sleeping, then uninstall that program.
But it doesn't sound to me like you have a problem.

According to the log file it drains 1-2% in hour (now I'm using aosp build, MIUI). I think, new Anker battery is the only way. Thanks to all!
Maybe in the future we'll get a more accurate battery driver...

Heavy battery drain

I recently flashed speed mods kernel on my galaxy note ddla5 rooted+cwm but instead of being a battery saver it became a problem. Everything is smooth and running but it drains battery like a big hole in a water bag. It drained 100% battery in just 6 hrs. Even the atock rom didnt consumed such heavy battery drain

So what's your question?

I want to prevent the battery drain and i also want to use the super awesome speedmod kernel.how?

You can become rich if you get the answer

You should try juice defender. It really saves battery, but when the processor is up, it drains battery faster.

Are you using a battery saver?

I'm using Green Power for a while now but lately I have been thinking that it might not be needed anymore.
What are your thoughts and what are you using to save battery.

Personally, I think they're a placebo effect, but I never gone in depth to do any real comparisons so I could be wrong. And the M8 has a good enough battery to where I don't consider needing a battery saver.

I ran Qualcomm's Battery Guru app customized for our CPU on my Rezound and now my M8, but ultimately decided that I would just run in standard powersave mode. My kernel lets me undervolt and overclock, so I get decent battery life coupled with fairly good performance without ruining any other battery software.

I use the built in batterysave in CleanROM combined with ART. Great combination.

I use the built-in Power Saver, along with Greenify.

greenify and wakelock detector here. tried all the battery savers on stock rom for heck of it and thought they drained my battery a little bit. Only one i know actually worked was deep sleep battery saver but i dont use xposed anymore so had to give that up

Same here. Greenify and wld are great. Very little resource use.

What ever for? [Imgur link, SFW; shows my battery stats this morning]
If I can get 20 hours to 30%, I can probably get 30 hours on a full charge. But I put my phone on the charger when I go to sleep. If I didn't, I'd be shooting for a 40 hour drain. That's kind of high expectations for a stock battery. Why not just charge it every time you go to bed?
I'm running the latest CleanROM in Dalvik mode, whatever kernel comes with it and zero battery saving apps. I do have the option ticked as you can see at the link where it cuts off your data when the screen is off (like Deep Sleep Battery Saver, and others). But the battery saver itself is off.
