Hi,
ever since last week when I updated to 2.2.2, my battery life has been crap. In the half hour it takes me to get ready and drive into work, the battery goes down to 60%. with 2.2.1 it was like 98% so something is messed up.
Nothing else has changed, no new apps.
I did the froyo update manually so I sort of know the mechanics of the process but I'm just wondering if I need to go back to stock and then to froyo and then the updates or if I can just download the 2.2.1 image and update with it.
thanks,
I have the same problem :/
Obvious answer but have you tried a factory reset? I would take a stab at it before using more aggressive solutions.
Failing that you can flash a stock rom using the passimg.zip method and OTA back up but at some point you will be back on 2.2.1 and getting nagged to update to 2.2.2 again.*
*It could be that i'm using the European varient of the firmware but i've not had the best of luck flashing back to older versions (It's a long story). Suffice it to say, every method failed at some stage so i flashed a 2.2.2 stock/custom ROM instead.
I'm getting consistent 20hrs+ to 30% running CM7 nightly. Can understand wanting to keep it simply stock and CM7 is pre alpha but my battery performance is about double.

Did I understand you correctly? You could only get 10 hours of your battery on stock rom?! And is there really a positive difference in CM7 battery performance? I know that some people (including me) had problems with that on CM6 so in my eyes CM is not the most battery efficient rom. Just curious..
About OP's battery problem. My N1 no different than before 2.2.2 update. Battery life seems the same. +1 for factory reset.
Cheers!
it could be time to root and go cutom
I had the same problem
And found out that it was google syncing (which i could not fix whatever i did). I wiped everything and started again.
This fixed it, however here are some tips to get good life on the nexus.
(This worked for me and saw my nexus 1 last 1.5 - 2 days before getting to 30%)
1: goto dial pad and do the *#*#info#*#* under phone set it from WCDMA to GSM perfered
2: Always use wifi where you can, wifi uses less battery than 3G, (this was a major saving in battery power for me) Set your wifi to always on (even when the screen is off). The 2 main places you spend most of your time is at home and work, set it up for those places and you will see your battery lasting a crap load
(my battery went from a drain of 7% a hour down to 2-3% by doing this).
This is a polite request that the wonderful chefs in this forum please look at the extreme battery drain issues that were brought up here... It appears that trying to run any custom rom on the softbank version of the device creates a huge drain.
I can run stock rom with custom kernels perfectly, so maybe there are just a few files that needed to be tweaked/removed from custom roms to prevent this drain.
Thank you for the time and hopefully there is a simple fix for this!
I am in Oki using a SoftBank 001HT as well and had the same problem till my phone took a swim and I got a new one. Softbank said they repaired it but I had a totally new serial number, the only part I got back from my original phone was the sim/sd card cover.
With my original phone Current Widget was reporting a -150ma drain in standby when everyone else was reporting -3ma. The only way I could get a -3ma drain was to have the phone in airplane mode. I am currently running CyanogenMod 7 with my new phone and now i get -3ma drain in standby with data on, wifi on, bluetooth on, and data sync on just like everyone else.
Try following the steps in this guide. http://forum.xda-developers.com/showthread.php?t=937080 And if that doesn't work try getting a new phone from softbank.

you just answered the question
by turning on airplane mode, you disable all radio functions. your battery drain stops so it's radio related.
try flashing different radios and see which one is the best for you.
I tried several radios and roms and still had -150ma drain with the old phone. I am using one of the same radios and roms that gave me -150ma drain on the old phone with my new phone and now I only have -3ma drain in standby.
My drain figures are just averages.

Thank you for clarifying that, cause i am on my 5th radio and none drain less than about 140ma unless in airplane mode.
So it must be something deeper than the radio.img...maybe a file in the ROM that wont let the radio ever go idle.
If someone could look at the files from a softbank japan ROM and compare them against the files of these other ROMs, we may be able to figure out the drain issue.
If anyone has any other ideas...please chime in!
Just for reference my stock ROM(the one that has no drain issues) is 1.35.762.2 CL277010
Just to clarify I am currently running CyanogenMod 7.0.0 stable release and radio 26.04.02.17 on my SoftBank branded 001HT with only -3ma in standby. I also ran it with radio 26.08.03.07 but my gps kept loosing lock. It was my old 001HT that had the -150ma drain problem.
The root and flash procedures I used were the ones on the on the Cyanogen Wiki page. I don't know if that makes any difference.

Looks like Softbank received a faulty batch of phones because I am having the same issues. Tried every rom/radio combo, but everything fails. ~150ma battery drain. The battery drain issue is getting rather annoying and I think I am going to do what you did and return the pos to softbank to get it fixed.
Did you root your old unit before returning it? If you did, did you unroot it before you went to the softbank shop?

It was rooted, Radio S-off, ENG S-off, Recovery Flashed, running one of the LeeDroid versons (even with -150ma drain with the screen off this rom gave me 6-7 hours vs. 3-4 CM7 was giving me), and I don't remeber what radio but it wasn't stock.
I was drunk at a bar when I knocked it in to the sink behind the bar and by the time I noticed, it was dead. I dried it with a hair dryer when I got home but it would not turn on so after I turned it in to SoftBank I dont think they could tell it was hacked or even cared since it was covered by the insurance.
I think hacking only voids the warrenty not damage protection insurance. Technicly if you brick your phone hacking it you damaged the phone and I assume the insurance would cover that. I only had to pay something like Y8500 and wait 2 weeks for them to "repair" it. They didn't repair anything, just gave me a new phone with a new serial number without the sim/sd cover and gave me my old cover back.
When I got my new phone the 1st thing I did was test it with current widget with the stock rom but the value was 0ma all the time. I went ahead and flashed it because 6-7 hours with LeeDroid was better then the stock rom and to my suprise i was getting the -3ma drain everyone was talking about so I flashed CM7 and still had -3ma standby drain. I thought it was SoftBanks network causing the problem at 1st, not the phone.
I don't think softbank users should assume that its a bad batch of DesireHD's just yet and try to get new phones. It could be other reasons and they should try the troubleshooting steps in the 2nd post 1st and try different rom and radio combinations and if they have tried EVERYTHING, then talk to softbank. I will post part of my 1st and 2nd serial numbers up when i get home and maybe they can be compaired or something then mabe we can confirm a bad batch.
I tried CM7 the last couple of days (which is very nice) and I didn't have any battery drain issues. That was my first Android Custom rom here in Japan on the Desire HD. I'm now playing with RCMix HD (also very nice) and I'll see how the battery lasts on that. I've not changed or installed any radios at this point. Are you sure you are using the correct APN etc?
(It can cost you a lot of money if you are not and your data bill is charged differently.)
On a second note: I really love this Touch Input keyboard in RCMix HD, and I'm not sure if the audio was better in CM7. If you try them out - please give me your opinions.
This is a double post reply.. I wanted to be clear that battery drain wasn't a problem with CM7 and I haven't changed or touched my radio. I'll see how RCMix HD holds up..
I am using Spike CM 7 right now. I like it a lot, but I'm only getting about 6-7 hours out of my phone now too. I need to figure out how to slow down the battery drain because it is super inconvenient to charge my phone twice per day.
My first phones serial number was:
HT0B6RX0**** <---- was BOUGHT 12/2010
Second phone was:
HT12JRXA**** <--- was MADE 03/2011
I am using CyanogenMod 7 and these are all the radios I have tried:
12.28e.60.140f_26.04.02.17_M2 <--- Similar to stock radio
12.28e.60.140f_26.04.02.17_M2_SF <--- Similar to stock radio
12.39.60.19_26.06.04.06_M <--- Poor battery life
12.35d.60.140f_26.06.03.24_M2 <--- Similar to stock radio
12.35d.60.140fU_26.08.03.07_M <--- Great battery life but GPS did not stay locked
12.48.60.23U_26.08.04.07_M3 <--- GPS did not stay locked
The ones that I say are similar to stock are similar in battery drain and performance. 26.08.03.07 is the only one that showed much improved battery life but the GPS would not stay locked.
26.08.03.07 would give me 3-5ma 90% of the time with 60ma spikes 5% and up to 200ma the last 5%.
Stock and the other similar radios would give 3-5ma 50% and 150-200ma the other 50%.
Others my get different results. I am going back to 26.08.03.07 and check to see if the battery drain is as good as the 1st time I used it and to see if there is something I can do to keep my GPS locked.
OK, I have a little promising news as far as the battery drain! I flashed inspired saga v 1.0.1 made for the inspire 4g and I was getting a drain of 3ma with Wifi on and 1ma with it off(while screen is off)! The extreme downfall though was that a lot of programs were force closing,messaging and phone were broke, and cellular data wasn't working either.
So it looks like we may be able to use the inspire 4g roms as a base to see if we can get a working GB rom on our "mystery" softbank phones
Hope this helps!!

Got my dhd back from softbank the other day. I initially asked them to have a look at it because of the horrible battery drain, and possibly replace it but no dice. They said everything was fine with the battery (well of course, the battery isn`t the culprit in this case) but they did end up replacing the camera and the proximity sensor.
Still trying to figure out the battery life issue though. I tried the saga rom but the battery life isnt too great with that either. Maybe its due to the radio working properly with the new rom?
Did anyone try the new softbank ruu? Wondering how the battery life is with the new rom...
Do you have a link for it. I would love to test it.

Make sure you have radio s-off before flashing though. Flashing the ruu will replace everything including recovery and bootloader so you will need s-off to downgrade again, if you need to, using and older ruu.

Hello everyone...
I have 2 issues with my Transformer
the first one is that whenever i leave my Transformer for couple hours it shuts down !! doesn't occur when charging but it does when it's not.. even when the battery is around 80% !! i had this problem with ALL kernels except the stock kernel which i don't wanna use !! also had this problem for around 2 months...
the second one happened today when i left my Transformer "Charged" at 100%.. and after couple of hours i found it shut down but when i powered it on again i found the battery 27% !!
i went to the battery stats and found that battery was decreasing slowly and there was a gap (which means that it turned off) and after the gap it shows the battery low !! it happened within 6 hours !!
Please help me if you can... !! I'm using Revolver ROM 3.9.5 and "Blades Kernel 3" that comes in the Revolver Parts...
UPDATE : The problem occurs with the stock kernel !!
This sounds very familiar to the problem I had with my Galaxy S2 a month ago.
It kept shutting down every few hours, and it was driving me mad. Then one day I uninstalled the app greenpower, and it was fine afterwards. You don't have the greenpower app by any chance? If not, maybe it can be caused by some other app you normally use?
The battery might be hosed. Have you ever let it hit 0 before? A lot of batteries never fully recover after being fully depleted once or twice.

I never heard of this app... Just like i said it doesn't happen with the stock kernel !!
But the reason I'm using other kernels is because i wanna Overclock !!

No i never let it hit 0%... but i don't think that the problem is in the battery
However I'll try it and see what happens !
sounds like a silly question but i have seen it alot. Are you charging through a computer(USB) or wall?
It could be related to setCPU and the according profiles. Just recently I saw that my profiles were messed up after updating ROM and kernel. Might be worth a shot.
Reinstall stock kernel Issue #1 fixed.
Issue 2 sounds like charger shut off and left TF on not charging.
You've pretty much explained to yourself why the thing is shutting down.. It works fine on the stock kernel but not one that is letting you overclock.. Sounds to me like you are either overclocking more than it can handle or undervolting to much or both.
I can almost bet that its not shutting down completely and its just going into a state that the screen is off but the OS is hung up, so its not responding to you turning the screen on.. This would explain why the battery seems to be dieing when its sitting idle.
Not sure about it dieing while its plugged in other than maybe a fluke.
I don't wanna use the stock kernel.. it's really slow !!
and i over clock to 1.4 ghz only since i can't overclock more than that because it restarts itself endlessly if i overclocked more than 1.4 ghz !! i undervolted about -25 or -50.. not much !!
Yes i charge it on a wall or anything but NOT on my computer...
How can i change profiles in setcpu ??

No no you misunderstood! DONT let the battery hit 0.
First, you need to use more exclamation points !!!!
sounds like you are suffering from deep sleep issues. What rom are you running? also, have you tried running a custom kernel and not overclock it? You have several variables that can be influencing your issues, start isolating what may be causing your problems. the kernel seems the must likely of culprits, I would clear the overclock and install setcpu and run it for a but and see if you can replicate your issue.

Just try the non stock kernel, oc it but dont uv it, not all devices can handle uv, even if it is only a little bit. Even take it back too 1000mhz and try to increase the uv and oc by little bits at a time to see exactly what your transformer can handle. I think its the uv thats causing the problems. Experiment a bit and youll find the sweet spot.
I'm using Revolver ROM and i mentioned that...
I've never undervolted till yestersay.. maybe it caused the second problem
I set the clock speed at 1ghz and i'm waiting to see if anything changes..
Yeah... the problem still occurs even after setting the clock speed at 1ghz and default voltage !! using clemsyn kernel ver 22...
Every device is different. Differences in manufacturing etc. You might have a picky device. Plus these are mobile platforms. No fans, just convection cooling. They are not meant to be tweaked and oc'ed they way we do. The stock kernel is very fast. What is it that you cannot do on the stock kernel that the extreme oc let's you do?

I'm guessing my device is bad and it's Asus' problem ! i tried setting the clock speed at normal 1Ghz but the problem still occurs !! the reason i overclock is that because with the stock kernel i get slower web browsing and slower flash playback and slower overall performance!! however I'm back on the stock kernel to check out if the problem is gone or not...
I doubted my device couple months ago... because I've seen everyone overclock their devices at 1.6 GHz Without any issues !! but when i try to overclock a little bit more than 1.4 GHz it restarts itself endlessly !!
Had the same issue a few months ago. Be prepared to wake up to a dead TF.
I sent it back to ASUS and they replaced main board and battery. Under warranty of course. I suggest you unroot and use a stock rom for now.

You stated in an earlier post that the problem does not show up in the stock ASUS setup, but only with a custom ROM and Kernel. How does that make it ASUS' problem. If you buy a car that says it runs on 87 octane fuel and you put 100% nitro methane in the tank and it blows up it is not the manufacturers fault.
Like others in the forum have mentioned, there is a very serious bug that causes the phone to just turn off when something more power intensive is turned on (especially mobile data).
I'm fairly sure my battery still holds a lot of charge after my phone turns off, and I'm getting poor battery life because of that. Changing back to old roms doesn't fix it, but I don't want to buy a new battery because I think this one should still be healthy.
So, my question is, what can I do? Is there anything else I should wipe besides batterystats.bin? Something a reflash or data/cache wipe doesn't remove? I tried to fully discharge the battery, but the phone always turns off much before it's empty.
Also, how can I be sure this bug wouldn't affect my new battery, if I were to buy a new one?
Your help would be greatly appreciated, thanks.

For better battery backup, I recommend you to flash "Fugumod" kernel v2.4 Beta 3 (Flash standard edition if 800mhz version causes lag). I have tested the battery life and I got 5-6 days backup (Wifi, Bluetooth, and GPS is on)

Thing is, I'm not getting bad battery backup. It's more like the phone just turns off if I actually try to use it. With mobile data on and to some extent wifi it just turns off in minutes or seconds. A full charge lasts for 2 hours or less with 3G on. I've tried other roms and kernels, including stock, but nothing fixed it.
For example, is there an app/method to prevent the phone from shutting down, only allowing a"hardware" shutdown? I mean only when the battery reached a critical voltage and stopped discharging for safety reasons, or something. Maybe that way I could properly calibrate it.

Hello, I have a Nexus 7 16Gb. I have been using it for about 20 days. Battery life was amazing. All of a sudden yesterday I noticed that i had a huge battery drain when using it. Installing Battery Calibration from the play store I saw that my maxumum charge was only 4 mV while it should be around 4200 mV. Is there a way to fix it or my battery is faulty. Have in mind that I have rooted it, and I have Codename Android rom, along with motley kernel v 1.1.1. I dont know if its a coincidence but just before I notice that drain I followed that guide. http://forum.xda-developers.com/showthread.php?p=30864511#post30864511

wow..well, apps do mess up sometimes.
and I dunno about everyone else, but to me the "Screen" looks like it's using a ton of battery. do you just leave the screen on all day doing nothing? the next runner up is only at 3%...seems a bit odd to me. Is the brightness all the way up or something?
Anyway if you reflash the stock rom and/or try a different ROM and you still have this problem, I think you will be able to RMA it.
did you get it thru Google Play?
Also, approx how long does the battery last on a full charge?

and I dunno about everyone else, but to me the "Screen" looks like it's using a ton of battery. do you just leave the screen on all day doing nothing? the next runner up is only at 3%...seems a bit odd to me. Is the brightness all the way up or something?
Anyway if you reflash the stock rom and/or try a different ROM and you still have this problem, I think you will be able to RMA it.
did you get it thru Google Play?
Also, approx how long does the battery last on a full charge?
Click to expand...
Click to collapse
Well when the screen is about 35% brightness. And I didn't mean the screen is draining battery. I meant when I am actually using the tablet its draining battery faster. I already flashed another rom and its the same. 3mv when its unplagged and 4 mV when its near charged...Do you thing I should flash the official image? I bought it from Tesco in the UK. Will I have a problem changing it?
Edit: Is it possible that the voltage reading is correct and the way its displayed is wrong? maybe the kernel reads 4V, but the app displays it as 4 mV? Any kernel experts? Thanks!
My N7 keeps showing 100% even though it's being used. :\ what's going on
Mine looses power when I have it charging lol
