[Q] Very Fast Battery Drain in MIUI 1.9.9 on Data

Hi guys. I'm new to the Android modding scene and I just installed my first ROM yesterday. Now my Droid Incredible is currently running MIUI 1.9.9 with the latest Incredikernel, undervolted by about 100 units.
When the phone is in sleep, the battery is no problem. Over the course of 1.5 hours I lost 2% of battery. However, I sat down and opened up browser (on 3G Data) to read a couple of articles, and in the course of 3-4 minutes, my battery went from 77% to 72%.
I don't know if this is normal, this is the first time using a text-based battery readout instead of a graphical, so maybe I never noticed it before...but I can't help but find this to be unusual. Are there any ways to fix this? Should I undervolt more? Switch to a different kernal? Flash my radio (I'm at Stock Froyo)?
I've looked around and can't find much on the issue (1.9.9 is new, I figure that is part of it), but perhaps you guys have some ideas for fixes?
EDIT: Upon closer look, it's only happening when using 3G Data, using wifi for the same thing and my battery has stayed at 71 for 10 minutes of browsing now. Also Camera drained 3% really quickly...but that was trying to use burst mode for 20 seconds, so I'm sure that was why, but just adding it as a note.

Battery Drains like HELL!!!

You are doing much better. I recently flashed 1.9.9 and initially it was choppy and lagged a lot. Then someone recommended Fugumod kernel. Although, it appeared as if the lags were removed, the display became dull and yellowish. I installed Voodoo color app to fix this issue to some extent but it was of no use..
This is just the beginning... I caliberated the battery yesterday and used it until 89% before I went to sleep.. Today morning, the battery had come down to 59% for no apparent reason. I searched the 'Battery monitor' for some information about this and found none of the services/apps were used for more than 15 minutes and yet the battery had drained the hell out.. The 'display' was at 60% and its duration was the max(~4 hours) and around 4mA of current..
To make matters worse, I rebooted the phone and the charge fell from 59% to 8%... just for a REBOOT!!! and Fugumod kernel doesn't allow me to charge with the phone switched off... This is annoying too.
I am severely disappointed I've never encountered such a disaster before.. There is absolutely no evidence as to what caused this battery drain.
Is there a solution for this? .. I'm charging my phone so that I can flash back to 1.9.2 and the stock kernel..
Any sort of help would be appreciated.. Thanks

[Q] Can't get a full charge!

Hey Folks, Just wondering if there are any other G2 users out there that have experienced this. For some time, I haven't been able to get my phone charges fully, and by fully, I mean something close to the reported norm of 97%-100%.
The hightest I got my phone was to 81% and that with a new battery, recalibration, and bump charging. In fact, I've had the phone powered off over night and upon restarting it, it was at 71%.
I've watched logcat to see if anything could be an issue there, I've installed ZDBox, (cool app, btw), and Battery Dr. The good news, is that after uninstalling a few apps and widgets, my battery life seems prolonged, (relatively speaking).
I'm running CM-7.1.0-RC1, 2.6.32.41-cyangenmod pershoot, and using the 26.06.2.27_M radio.
Since I couldn't get a full charge with it powered off, I'm thinking it might be a hardware issue or maybe the radio since so I might try 26.08.04.30 radio. Googling other forums, people were able to get a replacement phone from T-Mobile and some others said their motherboard needed to be replaced.
Any other ideas before I call T-Mobile?
Thanks!

Did you try clearing battery stats?

Yes, several times. Good call, though! By clearing the stats, I was able to get to the 81%.
Thanks!

Have you tried reflashing the rom? Maybe trying a different rom? Clear caches? I dunno I'm shooting for broke i guess....is it an aftermarket battery or stock?

Thanks, killj0y. Yes. I did that after posting. I did a Titanium Backup, then Nandroid backup, then wipe, superwipe, then flashed the CM7 nightly, (which is very slick, i might add). After bump charging I was able to get it up to 71%. I let it go down to 0% overnight and now I'm letting it recharge fully.
In about an hour, I'm going to call T-mobile and see if they have any other ideas.
It is an aftermarket battery but it behaves just like the OEM/stock.

You shouldn't ever drain your battery to 0% on purpose. You run the risk of the battery not being able to take a charge. Draining to 20% for battery meter calibration purposes is more than sufficient.

Yea plus aftermarket batteries can and do fail more often than stock. What brands is it?

Do you still have your stock battery? Try using that one and see how it acts. I'm willing to bet it's the battery.

The OEM battery I could never get above 71% and the new battery I have it up to 94% now and it isn't charging any higher.
I've had it plugged in for two hours. I have read the warnings about letting the battery drop to 0% and I agree, but I figure one time wouldn't hurt it. I got the second battery, thinking it was a problem with the OEM battery.
Ah! This happened as I was typing this. For the first time in a long time, the LED is green but the battery is at 94%, which I think might be okay.
Maybe the wipe/superwipe/reflash helped? I will keep you all updated and I sincerely appreciate the help and advice.

If that one time results in a battery that won't take a charge, then it hurts. Full discharge is also not good for the long term life of Li ion batteries. And it certainly doesn't help anything to run the battery to empty.

Yea I don't know how many times I've corrected people still quoting NiCd rules for Lithium ion batteries phone or otherwise lol. Anyways if the stock does the same thing it is probably the phone. Especially after a wipe, was it a clean reflash of the rom? Maybe that would work.

Here's my update. Kind of interesting.
So, by evening, my phone got down to 4% left of the battery. I plugged it in, (with my factory charger), and ZDBox said it would be 2 hours, 44 minutes until fully charged. Three hours later, it was at 45% full. I rebooted the phone and when it came up, it said it was at 86% full. Then I left it plugged in over night.
This morning, it was still at 86% and I rebooted it again, and then when it came back up it was 93% and within a couple of minutes, the LED turned green.
So, with this new batter, it *seems* slightly better, but I don't understand what's going on. This is weird, if you ask me.
The other bit of info is that at 7AM it was 93% and right now, (9AM, two hours later), my phone is at 72% with the majority of it being consumed by "Cell Standby."
I guess, since this is a new battery, there still might be some calibration/conditioning going on. I am still unsure if this points to a hardware issue with the phone.
Thanks again, for the help guys! I really wonder if I am the only person who is experiencing something like this.

Update: 19.09
Things have been a little better, but still not perfect.
I flashed CM7 Nightly, pershoot kernel, and 4.30 radio.
I have only been plugging in the charger when the phone drops below 20%. The phone only charges to 45% - 51%, then I reboot, and when it comes back up, the battery will read anywhere from 88% - 93%.
Once unplugged the batter rapidly drops down to the low 80's - mid 70 percentile and it stays in that range for a much longer time. Then once the battery drops below 40% is drains rapidly.
So, for example it says right now, "7h 54m 58s on Battery" and I'm at 20%. The breakdown is as follows:
Android system: 57%
Cell Standby: 12%
Wi-Fi: 12%
Phone Idle: 11%
Voice Calls: 9%
I'm really frustrated with having to reboot the phone to get seemingly get a full charge.
I think I am going to flash the latest nightly and then reflash the pershoot kernel and see where we are at that point. I still haven't decided if I need to call T-mobile since it could be a hardware issue.

It really sounds like a hardware issue to me. especially after several so many flashes and batteries...

Indeed. I called T-Mobile this morning and they are sending me a new phone. The guy asked me to inspect the battery, contacts, etc. He did ask me if I had put any "modified" software on it.
He also said, if they found modified software on it when they received it back at the shop, I would be charged a $108 restocking fee.
Quick, where's that downgrade guide!
Thanks for your help, everyone!

Update!
After I talked to T-Mobile, I downgraded my phone to the OTA Gingerbread and unrooted it, and turned S-ON. I admit, I was impressed with the OTA update since I had been running cooked roms since I got the think back in November 2010.
My new phone came today. Immediately, the battery behavior is completely different. I took out my battery from my old phone that said it was at 51% and put in the new phone and it said it was 80%. That's a good sign!
While we were at dinner, I got all the OTA updates, which really meant when I got home I had to downgrade it, but the guides here were really great, and I was back in business in no time.
I went with the latest CM7 nightly, the LEAK radio, and the latest pershoot kernel. I can tell already that battery behavior is much better.
Interestingly enough, on the stock gingerbread ROM, the DISPLAY was the major consumer of battery. Now on the stack I described, "Cell Phone Idle" is the biggest consumer. Maybe the stock T-MOUS radio is the best!?!? Who knows.
I hope this helps others who might be having weird battery problems. Have a great weekend!

I'm having this exact behavior where I can't get past ~73% without rebooting, then it goes to ~93%, which is about as high as I can get it. Guess I'll call T-Mo, I've seen it with different ROMs to I figured it was probably hardware as well.

Hey Thermalx, I hear you! The replacement phone I got from T-Mobile is behaves completely different. I have kept a charge +26 hours. I never thought I'd see the day!
Let us know how it works out.
Thanks!

[Q] Instant battery drops

Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?

Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.

Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS

That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?

Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.

Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.

Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.

Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.

so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.

Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

These are my overnight stats when I was sleeping. It's usually worse when wifi is on.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.

Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.

figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.

FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml

Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.

Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?

[Q] What's wrong with my battery life?

I'm close to buying a new phone because the battery life on my One X is HORRENDOUS.
I'm on Viper 3.4. Ever since I upgraded from what I think was 2.7, my battery has taken a massive, massive decline in quality. I flashed AOKP and it was terrible, so I went back to sense and it just...wasn't the same. The standby time WITH wifi and autosync on the old Viper had me losing about 1% per hour, sometimes less.
After going to AOKP and then back, it just hasn't been anywhere near as good. And now that I'm on 3.4, it's just ridiculously bad.
This is my battery life from Friday. I woke up at about 8.45 and unplugged my phone soon afterwards. Used it a bit on the way to work at 10, then I checked it every now and then for new messages, and maybe responded. I finished work at 6. At this point I was below 50% despite barely using the phone at all. On the way home, the battery just completely shat itself and dropped to about 18% by 8pm.
Something else odd I noticed, you know when the phone heats up when you're playing games and stuff? After receiving a phone call that I ignored while I was at work, I could feel the phone becoming extremely hot in my pocket (I didn't even take it out!). Why?!

Download antutu tester and do a battery test.
A kernel is how ur software interacts with your hardware. flash one and see if it helps u out. I get 12-16 hours battery on normal everyday use with a kernel

Really desperate here...

My battery discharges pretty quickly and I just don't know what to do anymore...
It usually goes down pretty fast when I'm connected to wifi. I think the main culprit might be Kernel (Android OS). Please take a look at some screenshots I took while using the Gsam battery monitor app and Better Battery Stats app and correct me if I'm wrong.
I have stock ROM, stock Kernel and my Radio version is: 5.1204.167.31
What do you think I should do? Change the Kernel, Radio or maybe both?
And if so, what would version would you suggest for my stock ROM?
Or should I just replace the battery and hope that fixes the issue...

Wifi will definately drain it quicker, usually keep mine turned off until I use it. Depending on how old the phone is definately affects battery life, mine is now just over 2 years old and I find that although it charges to 100%, it will drop to 91% in the first 5 minutes of using it. HTC has a self test in the dialer enter *#*#3424#*#* then follow through to the battery test. I think phone needs to be in airplane mode and has to be fully charged, then leave it on for an extra hour or two. Test takes an hour and from memory if battery is above 70% it passes.

Mine does the same. It drops to 91% fairly quickly after charging. I did the HTC battery test about a month ago and it showed 81% battery left after the test (it said that if it's below 70% the battery might be faulty).
Since I made this thread, I managed to change the stock kernel and now I'm using Alex's kernel. The battery usage is much better but still the Android OS or kernel drains much of the battery.
Do you think changing the battery completely I might have better results?

Before Alex's kernel, I tried XM's latest kernel because I read on OP's thread that it works with stock ROM too, but I never managed to boot my phone after flashing it. (and I did everything right I think: cleared fastboot cache, fastboot flashed the boot.img then flashed the zip in recovery)
I am all for trying lyapota's kernel but the download links have been removed in the official thread I think. Can you provide me with a link for downloading please?

Only one option left, to try and remove some bloatware stock apps and see if that changes anything.
