Battery drains faster than it should

Hello there,
I would really like some advice - my battery is draining like water. I'm quite convinced it is the regulation of the unit; I bought a 2400mAh battery replacement and it lasted ages on first go, but then my G1 started draining stupidly fast after I'd recharged it. This also happens on the stock battery too (buy even quicker!). I'm convinced it is the regulation because a) I've never had battery problems previously and b) the battery meter starts at about 26% when I plug it it in (after the phone shuts off from it being dead and I then plug in the charger).
I actually have a bricked G1 that still charges batteries, so I thought I'd do an overnight charge on the battery that way, to 'remind' the other G1 what a 100% battery is like, but that didn't seem to work either.
Can someone help? Is this a known problem? I would really appreciate any advice.

Things that cause ridiculous battery drain;
Backlight, keep it at no more than 30%
Wifi - turn off search for open networks,
Gps - wow does this drain

GPS doesn't really drain battery unless it's actively being used...at least not on my phone.
You can also try disabling 3G if you're not in a 3G area. It will keep trying to find a 3G signal, which really drains battery.
For the record, I have a stock battery that I get ~13-16 hours on from a single charge... my backlight is at 40%, GPS is always on, and I use wifi whenever I want to surf the web and am near an open network.
OP...if your battery is lasting you only a couple of hours, then I'd try to reflash your ROM. Might help...

Wow 13 to 16, I am lucky if I get 6 with 30% backlight, and wi-fi and gps off, I have always gotten that on ever rom even stock with no widgets, you are one of the very few with good battery life cause I have seen many complaints about short battery ranges

Yeah, that's on a normal, moderate usage day. If I use it heavily, with a lot of wifi and web browsing, then I'll get around 10.
Maybe your battery needs to be replaced... could just be old and not holding a charge properly.

It's 2 months old, has done it from day one, I also have another battery that does it too that I kept from a previously brick g1, so one 3 phones, all the same battery life but then I use it quite heavily, always browsing on the web since my computer burned out

try that? 3rd gen battery could help..

Thanks for the suggestions, but it's not a wifi/3g/brightness etc problem - I've had a G1 for six months, I know exactly how much power should be consumed. It's also not the battery; I have two stock batteries and a brand new 2400mAh battery, which for the first few charges lasted about 2 - 2.5 days and was brilliant (as it should be), but now doesn't last all that long.
I may have made the situation slightly better however - I did a Nandroid backup, wiped to factory (well, Cyanogen 4.0.4 anyway) and booted into that. I then restored the backup and when I plugged back in to the charger, the meter was at 85%, and seemed to take a normal amount of time to charge (and not jump to 100%). It remains to be seen if the problem is solved, I've yet to have the battery drain (this is a good sign though) an plug in the charger to see if it will jump from 0 to 25 or not.
I'll re-post when I know.

run the battery down until the phone shuts off without plugging it in.
charge the battery while the phone is off over night
do this 3-5 times and see if you get any improvement.
also remember some of the cheap 2400 batts from ebay and such claim 2400 but that is from 3.5V to 3.0V. The G1 considers 3.2V to be dead so you only get from 3.5V to 3.2V which sucks.

I'm with gridlock on this one. My batteries suck. It always needs a mid day charge. And to the poster that said to reflash a rom, that is bad advice. There is known issues with getting poor performance out of these batteries. I have 2 and both do the same. Got the second one from complaining to t-mo about how bad it sucks.

Reflashing seems to have worked...the 2400mAh battery seems a lot better now, it lasted nearly two days (it runs at 3.7v, according to my battery diagnostic), I've only just recharged it last night. When I plug it in, it charges normally and linearly now, instead of jumping straight to 25%.
So my advice, if anyone is having similar problems to me, would be to try a reflash.
Thanks for your help everyone.

Battery life for the Nexus One

I've been hearing complaints about battery life with the N1. Fortunately I have'nt had that problem, but I did notice that my batteries don't fully charge even though the power indicator is green. I have two batteries, a standard and extended, and I checked the status in my settings and it said the battery was charged, but it only read as 94%. It would'nt charge past that while the phone was on. So, I turned the phone off and the indicator turned red, telling me the real state of the battery, so I let it charge in off mode until the battery light turned green, and it charged 100%. I notice with all rechargables when we first get the battery the first thing we do is throw it on the charger, when we should actually use the battery until it's dead, then give it a full charge. I did that with both my batteries, the one that came with the phone took about 5 or 6 hours to fully charge, and the extended one took a couple of hours. My battery indicator has about 5 bars in it, now I lose about one bar every hour, and my drainage never goes below 50%. And it's not like my phone is idle, because you know I have to show off my latest gadget, and I push android on everybody I know. So I let them browse the web, tweet, go on facebook, wifi tether, play games that support flash, take pictures, listen to music, explore the app market and play with all the apps we have, not to mention I'm making and recieving calls and checking my emails, and still my battery never goes below 50%. Idle I never go below 70%. Try my little method and see if it works for you
Rooted N1 with locked bootloader
FRF83 eViL n-One-shOt Noir IV Redeux (I took out some apps in my kitchen)
Kernel version:2.6.34-925mVCFS-OC-Monks-062610
8GB class 6 sdcard
512 ext3 partition/no swap

Thats how i usually charge my batteries too, and i dont get the same results. Maybe i need to shut off my phone.
Slow charging your battery also helps, too bad the battery doesnt charge that way. I use a third party dock/charger for HTC desire (Which uses same batt as N1) and it charges really really slow. The battery is cool throughout. And the battery life is astounding. Though not as long as yours. :\

Since i've had this latest Froyo update.. my battery has been GREAT. The best it's ever been by farrrrrr. When I manually updated the last time, my battery was horrible for a while.

What is this "extended" battery???

For me, I think the battery is average. It's not great,but it's not horrendous either. It's just that there's so much you can do with the phone, that you start using it more, hence the fast draining of battery.
At first I felt the battery was really bad, but when I come to think of it, I surf on the web, play games, etc. for like 5 hours each day. ( I know I'm a bad student.) This is with auto-sync, auto brightness, and my battery is almost dead around 5pm. It could be better, but oh well...

Froyo has greatly improved battery life to ridiculous levels.

Yes froyo has doubled my battery life by 5_6 hours

Extended battery

It came with my phone. I purchased my phone on ebay, and It was used, I got a dock and extended battery. I don't know if the dock came standard. I think it was a good deal though, I just visited the site where the guy bought the battery, and it cost $70 and I know the dock cost about $40. I won the bid @ $454, compared to the $580 I would have paid @ googles site. Check the link to see pricing.

Check out this post that includes instructions from an HTC rep for better battery life:

I can confirm it works and so can others. It seems it is best to charge the phone when it is off.

X10 battery drain solved - by buying a new battery

So I always assumed the battery drain was a hardware or software issue, especially as my X10 would often shut down on 40% power and refuse to stay turned on unless the battery were taken out for 5 minutes.
Rather than buy a new phone I thought I'd try a new battery (I have had the phone since August 2010) - just £3 from ebay, and since then my battery life has been astounding - I'm quite a heavy user, but would almost run out after 8-9 hours despite keeping everything off and only switching on 3g and wifi when necessary. Now I can leave wifi and 3g on all day, leave the phone at medium brightness setting and still have 40% after a 15 hour day of medium-heavy usage.
I used to get idle drain of 1% every 10-15 mins as well (unless the phone was rebooted), but that seems to have disappeared as well.
So before you give up on it, do try a new battery, especially if you've had yours over a year. If there's no effect, you've lost £3 and still have a spare on hand.

Hello friend,could you please post the link where did you buy?

You think people on here throw their phone away because of battery drain,and it doesnt cross their minds to buy a new battery.....instead of buying a new phone.
I just hope your £3 battery doesnt damage your phone........or explode when youve got the phone in your pocket.......or during a call

Whats the size? i have a 1500mAh and a 2600mAh whats ur cpu settings also? looking for a good setup thanks in advance!
Also amazon link for 2600mAh btw its a big battery, and requires its own case which is rather bulky (http://www.amazon.co.uk/Sony-Ericss...TIMS/ref=sr_1_1?ie=UTF8&qid=1331594837&sr=8-1)
This is the 1500 i currently use, still getting the battery sorted with kernels ect
(http://www.amazon.co.uk/KC-Electron...1?s=electronics&ie=UTF8&qid=1331594882&sr=1-1)

I would just like to confirm what OP wrote. Not only did my new battery (I got the 1800mah one from Mugen, $33) solve my battery drain, it also solved my mysterious reboots, lockups, and heat issues. My phone would regularly get up to 48 celcius, it would result in it automatically shutting off the charging. It was a pain in the butt when using GPS on long trips as I would have to have the AC run straight onto the phone just so it would still charge. It was like this from new. With the new battery it has not budged above 29 celcius with GPS navigation, 100% screen, bluetooth, music and sync all running at the same time, I am shocked!
In order to condition the battery I turned off the screen timeout ("No screen off" in the Market) so I could get it to drain to 5%, it lasts twice as long even with the screen on all the time then it did before I got the battery, feels like a new phone.

beware of cheap batteries
beware of counterfeit batteries. Ive read a bit about cheap batteries being inferior knock offs. You tube has several vids about how to tell the difference

I'm about to buy bigger battery for my x10i. Now I have original 1500 mAh. Do you, who already tested thease 2500 mAh bateries see the difference?

My phone starting doing the exact same thing... shutting down at around 40% so I order the Mugen 1800mAH battery as well. Should get it in a few weeks... I did see much cheaper batteries available but figured you get what you pay for, and the reviews on the Mugen batteries seem to be good so I spend the extra money for it. Looking forward to the extended battery life!

Second HD2 battery drain problem

hi everyone,
i have HD2 for 3 years (his battery drain in standby is 5-10 mA) and recently i bought second one, and I'm having problem with his battery drain in standby it never goes under 40mA (with airplane on is the same thing). i did task 29, put the same radio (2.15.50.14), same clk and same rom (NexusHD2-ICS-4.0.4-CM9-HWA V2.7), I try juice defender and it is always above 40mA. On cpu spy I see that phone is in deep sleep 90% of time (similar like my first HD2). I try couple difrent roms and it never goes under 40mA in standby. i swap battery an it didnt change anything. is there anything that i could try or is it that some HD2 just cant get normal standby battery drain? what should I do, any advice will bi appreciated.
thx in advance

Seems like you've tried a fair amount, the only thing I can think of is that the hardware of the new HD2 is somehow faulty. Is the same issue present with all ROMs?

yes, with every (four) ROM standby battery drain is above 40 mA, I could try put back win 6.5 but that isn't why I bought this phone

A long shot, but perhaps a dodgy battery pin? Or maybe a dirty connection plate on the battery?
Have you switched the batteries to confirm its the phone not the battery?

yes I switch battery and it is the same, still big battery drain on second HD2 and normal on first. battery pins are clear an they looks to be good.

update,
first I put back win mobile 6.5 and battery would drain from 100% to 0% in 30 hours in standby , it is little bit better than android because on android battery last around 16 hours but still it is short standby time. After that I switch just motherboard from bad hd2 to good one and battery drain was bad where the second motherboard was installed, so it is something with motherboard or cpu or gpu and it is hardware problem. Maybe stronger battery could help bit, don't know what to do next

i reckon that 16hrs when its on android is good for a hd2 i have a hd2 with extended andina battery in i JUST get a full days use (ie 8am 2 10pm) with normal use thru out the day no mater what rom i have try'd and tbh ive try'd a lot and there on par with each other but if you have all the stuf on ,gps Bluetooth then i get about 6 hrs from it
as i have said b4 this phone was never ment to run android hence why the battery is better in winmo

I agree with you it that it isn't made for android, but there is to big deference between two hd2 that i have, anyway can you send me link of extended battery and what capacity is it?

http://www.ebay.co.uk/itm/HTC-HD2-T...808370?pt=PDA_Accessories&hash=item3cc10bb7b2
i dont know ware you in the world but you can search worldwide id wait if you cant get one and see if one pops up ,also these gold hd2 batterys you see on there are crap ive try'd one there no better than the htc org battery the andida has a good name but you get what you pay for
have you tr'd a bigger partion on it you may have bad blocks or could be or have been overheated in the past (processor) thats also common i use the nexus 4.0.4 rom and i find it ok

to be honest i don't know, i got it last week for low price as used phone whit win mobile on. i did tray bigger partition it didnt help. but i think it might be damaged because last night I turned it off when it was on 20% battery (to save battery) and this morning I couldn't turn it on, battery was dead, so i think it has some hardware malfunction. i will try to find bigger battery (double size in capacity and in size), also don't believe in gold battery , not for that price, thanks for replay

Phone shut off at 32% and only charged 7% in 1h30m with fast charge

I work 8 hour shifts and my 6P on Pure Nexus lasts through the shift with ~30% when I get home.
I was listening to music through Bluetooth and when I turned off my headset around 5 hours into my shift, my phone shut off and wouldn't turn on. I was in and out of the freezer, so I thought it was the cold. I got home, turned it on and plugged it in and saw it had 32% left.
An 1h30m of charging and it only charged 7% which is really unusual and is the first time.
I have AccuBattery Pro and it is saying it's going to take 10 more hours to fully charge using fast charge. Android lockscreen says "Charging rapidly. 12 hours until full."
Also in AccuBattery, although my design capacity for the battery is 3450 mah, it normally says estimated capacity is 2200, but is now saying I have over 5000 mah in capacity.
When unplugged, it has a screen on discharge rate of 50-70%/h when the average is 23%/h.
Is the battery dying? I thought it would gradually decrease in capacity and not suddenly change overnight.

When my battery bug hit..it just hit. No warning signs or anything. I was crapping out anywhere from 60%-10% and everywhere in between. I bit the bullet and RMAed for a new battery (they gave me a new screen too for whatever reason) Before i sent it in my Accubattery stats were saying i was at 75% capacity and now ive been at 100% capacity since i got it back and i can happily go from 100%-0% like its supposed to.
Although your situation does sound unique its almost certain you'll need a battery replacement.. or try a new ROM and see if it keeps happening.

Unfortunately, I got my phone from Rogers around November 2015. I don't even know what they can do about it. It's been averaging about 14%/h charging which is about 1/3 the speed. I've been using the same ROM for several weeks with no issues and haven't installed anything new lately other than app updates. I can try upgrading Pure Nexus, but it seems like they have a power menu bug at the moment.

Do you think your charger could be broken?

My wife has a 6P also. I was trying her charger and it's the same thing. I've rebooted twice. It's still draining at least about twice the normal average when disconnected.
So it's roughly draining at about twice the normal speed without doing anything and charging at a third the normal speed.
I seriously can't afford to replace it. I regret choosing a phone without replaceable batteries and will not do that again, which means no Pixel phones. At least I still have my Galaxy Note 3 which still works.

if i were you id backup the entire phone (or whatever is importannt to you) to my computer and download the J factory image and do a fresh clean flash and pray that it clears out whatever is going on. Sucks to start fresh, but worth a shot

I use FolderSync to backup my phone nightly to my NAS server.
The slow charging speed may be due to high cpu temperature. It was hovering around 40° for whatever reason. I set it down on a cold granite window sill and the temperature dropped to 35° and was charging at twice the speed, but still slower (1000mah vs 1550mah from before). I've been holding it for a while and the temperature is again going back up with charge speed slowing. Again, I've never had this happen before.
Thanks again, I'll probably restore the phone and bring it to Rogers later this week to see what they say.
