Anyone else notice this?? I've run both the first and the second 2.2 leaked Rom, and both exhibit this same issue. Okay first a little info: stock battery, stock HTC wall charger and stock use cable. I don't charge off a use port on a comp, always the wall charger.
Now, on stock 2.1, I could run the battery all the way down, connect the charger, and be back to full charge in max 1.5 hours. On 2.2, it takes more than twice that long. So I went thru the whole downgrade process (pain!) to get back to stock 2.1, ran that for a day and confirmed, charging on the wall charger gets about 1% a minute. Went back to 2.0 radio and second leaked 2.2 ota, and yeah, back to taking 2-3 mins to get a percent, about 3.5-4 hours to full charge.
So..... what gives? Anyone else noticing this? Can it be fixed via patch or something? Is it the radio, the new kernel, what?
its probably the new radio. i dont know how the radio directly affects battery life tho. it is not the kernel, because i am running cm6 and the problems have persisted on cm6 too. i have been experienceing these problems too

The radio could be the #2 drain on a battery (short of 100% on screen) ... if the radio is not getting the signal it wants, it hunts and hunts, and 1x draws incredible power from the battery vs 3G.
The buggy radio and buggy beta could easily be causing you trouble in your area, if they just don't play right with the signal you are getting. Hopefully when the non-beta radio comes out, things will change.
Mind you, my battery life seems fine, no worse than stock anyways. It's just the charging time that has gotten dramatically worse.
Same..there's no reason my phone should be charging for close to 4 to 5 hours I don't know what's up with that

I may be all wet...but there is a battery file in your phone that I think gets wiped when you install a new ROM.
I do all of my charging at night, so I don't know how long it takes after wiping and installing ROMs. I do remember it taking about three hours to charge the battery the very first time I plugged it in.

Doesn't explain why after I wiped and went back to 100% stock my charge time went back to taking no more than 90 mins...
Nah I flashed roms all the time on my Droid never took this long to charge. Even on my inc cyanogen 6 never took that long its definitely something about 2.2 roms or sky raider.
I have this problem on mine and made a thread on androidforums. After watching a few things I came to the conclusion its the cpu speed. It never throttles down below about 500-600 mhz. Open setCPU and don't touch anything. You'll see it won't drop to the 200s like its supposed to.
Someone came up with a work around by using setcpu. Create a profile for when the screen is off so that the max is 245 mhz. You'll find that your charge times will be a lot better.
Even though this works I would like to know why the phone is not throttling down at idle like its supposed to. Someone with more knowledge might have the answer.
I had noticed that and posted a thread about it awhile back. I have a hard time believing that is the sole reason for tripping charge times though

all the explanations posted so far would be a cause of battery DRAIN issues, which most people claim to see better overall battery life since jumping on 2.2 (myself included). none of these could explain why charge times would take twice as long. i myself have had better battery life on 2.2, but charge times are definitely in the 3-4 hour range as opposed to the 1.5 hours it was before. BUT, one theory is htc might have lowered the charge input from what it was before, meaning a slower charge time but preserving battery health and possibly increasing battery life. just a guess, chemistry majors correct me if im wrong lol.

If the phone isnt underclocking even when the screen is off, it would be using more power even while charging, which would explain the long charge times.
Proof of concept would be, if you try and charge while using bluetooth and gps in the car you may not lose charge, but it will not charge as quickly as if you are not using those things.
if the CPU use is high then the battery would not charge as quickly.
I'm still not so certain that the setcpu profle has solved my problem, still havent been conscious of it enough to be sure.

Common sense would tell you that if something is draining the battery, charge times would be higher...
Gbenj. Its definitely not a full fix for it since it requires the screen to be off but it has definitely cut down on my charge times. Its still no where near what it was for 2.1 but atleast I dont have to wait 4 hours for 10%.

All understood, BUT, yesterday when using gps nav for a few hours and on the car charger, i was actually still LOSING battery. nothing else was on (bluetooth or wifi) no calls, no texts or anything. 2.1, i still gained charge while using gps on the car charger as well as having an overclocked kernel. so its definitely not a cpu issue considering peak processor speed has not been tampered with.
Just a thought but perhaps the FROYO Rom that you flashed has a fix in it for the problem with charging. In otherwords perhaps it is actually charging the whole battery. I haven't paid any attention to mine as to whether it is taking longer. I usually just charge while I sleep and then while I am in the car and sometimes at my desk if I plan to plug in for something I will just leave it plugged so I get more use of higher drain features when I go home. I noticed though that if you bump charge as recommended, (pre-update) I only did it once and saw little to no improvement, it took for ever. After I charged it to green, I turned it off and charged it to green, unplugged it plugged it back charged to green, and repeated until it was green when I first plugged in. Now it seems to me that the problem is a software/system issue so it would be plausible that a software solution could be developed. I haven't tried since I updated and the ROM I am currently using gives me the same battery life I had before but now I can leave GPS on all the time something I couldn't even think about with Stock everything.
So I may be wrong but it may be that it is taking longer to charge because it is actually charging the chunk of battery that it hadn't been charging before. Just a thought and since I am pretty sure I don't have the same ROM you have I won't venture to test and post results but perhaps you could.

bump charging is still required by anyone on 2.2 so its not charging any more of the battery than what it used to, just a lot slower.
Agreed, it doesn't make bump charging any less required for "full" charge, also, this theory would mean we'd be getting significantly better battery life.... I most definitely was not.
It's possible they reduced the charger output to the battery to increase battery life/reduce heat while charging.

if by battery life you mean overall battery health over time then yes, that is what i believe as well. also, these leaked froyo roms are all developmental, not final releases. im guessing that they may have tried a fix for battery issues but it didnt work out right in these roms so im hoping in the final release it will be truly fixed.
has anyone noticed that the battery stops charging after a while? it almost seems like the system is stopping the charge because its running for so long. anyone seen anything like this?
My Nexus 4's battery indicator behaves very strangely. It often gets "stuck" at certain values and then drops suddenly by 2-3%. Other times, it'll drop like a rock before getting temporarily stuck at another value.
This wouldn't bother me so much if the overall battery life was acceptable, but it isn't, no matter what ROM/kernel settings I've tried. I logged about half an hour of screen-on time earlier today looking up some stuff, and I'm already down to 75%.
Any idea what's going on? I'm trying to figure out whether my Nexus 4 is defective or not.
You likely have an app running in the background eating CPU processes. You can install CPU spy to see if your phone is going into deep sleep, and better battery stats to see if there is something keeping the phone awake or using processes. Lastly, someone will suggest wiping your battery stats. This is not necessary because they are wiped every full charge by the OS.

I've already inspected my battery life with Better Battery Stats and CPU Spy. There's nothing to explain it.
CPU spy reports that my phone has been in Deep Sleep 84%, 384 MHz 11%...and 1512 MHz 2%.
The highest wakelock reported in Better Battery Stats is AquaMail checking for messages, clocking in at a very reasonable 2.3%.
I've found that when your battery stats report erratically that your battery may need to be replaced. Usually faulty batteries drain quickly and raise and lower the reported level while it's discharging. Has your battery ran really hot in the post that may have caused damage?

No, not that I'm aware of. This device is only a week old, and the hottest it's gotten is when I used it to stream music to my car's stereo via Bluetooth. The battery drain was absolutely INSANE with that, by the way - I dropped about 10% from five minutes of streaming YouTube. EDIT: And yes, there have been a few instances where the battery has magically raised the battery level.
Of course, if I tell Google that I think my battery is defective, they'll have me send back the entire phone rather than just the battery. Sayonara, fastest binning! :crying:
Unless someone can suggest something else to try, I'll probably contact Google for an RMA. Le sigh.

True dat. You would still be better off not having to deal with a defective battery for the long term though.
I wouldn't exactly call this an issue because it doesn't really affect how I use my phone - it's merely something odd that has me curious if anyone else has it:
If I charge my phone all night, and plug it out at 100%, then no matter what I do it'll stick to 100% for a long, LONG while before it hits 99% - we're talking..25 mins of sat nav, and spotify, and full screen brightness on the go. But then, it falls down into a more regular pace of discharging.
If however I unplug it 5-10 mins after it hits 100%, it starts discharging normally.
I think I can get a batter life of full browsing of 6 hours, probably. Maybe a bit more (never tried it, never needed to).
I am just curious why this happens with my LG. Do you think it's a fault or is it fairly common?
Thanks
P.S. - testing it again now - 15 mins in youtube watching a video, still at 100%. very strange
you seem to have found some interesting sweetspots of charging and battery depletions.
My instinct tells me the discharging and the 100% mark is influenced by code in some way other then the battery being truly at 100%. There is software like android tuner or battery widget that monitors stuff.
however a great dev already wrote something about tinkering on lg's side in reporting the battery. Which means the percentage is. indicative but completely reliable. To gain more indepth into the actual battery usage other apps are needed. If have battery ocd that is.
I would report this to lg, just to be sure nothing else is happening

what is more interesting is that this happens to me both on official LG, and on ROM (cloudyfix).
Continuing with my tests, I have been running youtube on repeat since unplugging and monitoring. I am now at 50%, with...close to 5 hours of usage?
then its playing from buffer and not continiously downloading and streaming right?

It downloaded all times. I plugged the phone in to charge at 10÷.at that time I had 7:30 hours YouTube screen time on auto at 90÷ . I suppose this is a good performance?

yeah i thought so.
So I'll leave with that little flaw I think, I'll just learn not to mind it and be sure to always charge overnight to get the best next day. Thanks for the help
I usually charge my phone and reboot it right after it hits 100%. I don't disconnect the charger until the phone restarts completely.
Doing that I get outstanding battery life
Battery drain with or without wake lock, doesn't matter. :good:
It has nothing to do with Android, on average i'm getting 3days with 6-7 hours screen on time on every charge.
So either you have app that drains battery or your battery is malfunctioning. (or both)

Well, I don't think it's an app that is draining battery as, there are no wake locks and I don't use apps that run in background except Google apps. I don't think it's a hardware error either because this doesn't always happen. It started to happen a few days after I got the Nexus 7 half a year ago, then stopped and started randomly. It hasn't happened for at least 2 or 3 month until one week ago.
I also own an Android phone(a Samsung Galaxy S2, I know it's old) and wake locks happen so frequently, sometimes I wake up (after only 6-8 hours) to my phone having discharged completely. Betterbatterystats shows wake locks on my phone most of the time but they are so generic and not attributed to an app(i.e show up in the partial wake locks tab) that I can't troubleshoot. And why do I always have to troubleshoot? Why would I have to turn off all services to ensure I get through the day with 1 charge. I don't even use my phone a lot.

Let us see the BBS logs for your phone.
About the tablet, flo has never had good idle drain, but this is likely a problem with your wifi. Before you go to bed, turn off wifi and reboot. See if you can still reproduce the 3.0%/hr drain.
If that doesn't make a difference, recommend trying stock ROM and especially kernel.

Is he using a NON standard rom and the guy is *****ing about battery problems LOL
One word of advice, regardless. Do not let your battery drain completely. Ever.
Lost my Nexus 7 like that, the battery life is great so I was lazy to enough to charge it before going to sleep (it was on a very low level then). Got a thin brick in the morning
Charge it before hitting 20% battery to be safe. That is what I do. It expands battery life longer for me

It does work besides there is no damage if you let it die just a few times but if you let the battery discharged till it dies frequently then you are damaging the battery. This is more common on Li-on battery as they drain more quickly overtime due to frequent loss of power.

Hmm. Good to know, thanks. I rarely let stuff die completely, but now I'll actively avoid it.
I have been trying to find a solution to my problem from quite sometime now.
When ever the battery percentage goes below 30% it suddenly drops to 15% and shuts off the phone in 10seconds or so. It happens very quickly.
I don't think this is due to some software as i have tried almost all stock roms as well as custom roms.
Battery drops insanely fast! Anyone else facing this too?

Yesssss! Same thing, it's so annoying, I was just about to post this, let me know if you find a fix for this, I've been looking at like wake lock detectors and using greenify and all that, but there's definitely something wrong with the software, I also tried a bunch of different roms and kernels, idk hopefully someone knows something about it

Have battery replaced (either by Google or Huawei depending where you purchased it from)
It's due to voltage dipping too low at lower percentages. Defective Battery
