I have a slight beef about my 8525. Sure, it's a great phone with a lot of features, but that only goes so far when the battery life is terrible. I came from a RAZR so maybe I am expecting too much, but I can start the day with 70% battery life and take a couple pictures and browse the Internet for a few minutes (under 10) and end up with 40% battery life by the end of the day. I'm not keeping Bluetooth, WiFi or any Cingular connection open and I am leaving the phone in standby. It seems like anytime I do anything, the battery life goes down 10%. The only software I have installed is Google Maps mobile. Is this normal or am I expection too much out of this thing?
I have done the registry edits for better battery life and conditioned the battery properly when I got it. Will a different radio version help (I currently have 1.40.30.00 on WM5) or WM6 help?
I once placed a 45 minute call and the battery life went down 20% just by doing that.
Am I being too picky?

I've seen people say that some radio's gulp power like crazy, so u cud experiment with different radio's.
I'm on 1.47 rite now and I talk a lot of my phone, use google maps, browse the web, and I charge my phone once every 2 days or so. So its pretty good, i think for the amount of functions the phone has.
I just did a search for battery just in this forum, and in the title of the thread and found a lot of similar complaints so I don't feel so bad now. I also did the registry edit that allows the BAND tab to show under the PHONE settings so I can manually lock my phone to EDGE most of the time and select UMTS only when I prefer the additional speed. One would logically conclude that locking the band would help battery life. We shall see
Radio 1.40.30.00 seems to be a radio version most people are content with so I am stick with it for the time being.
Battery Life
I had an 8125 for almost a year and it was usually good for a day or so.
I recently dropped the 8125 into a cup of water... Amazingly it was not submersible. So now I have the 8525 here in Los Angeles.
The battery life is pretty pathetic. If I unplug the phone in the morning (around 10am) and just carry it around with me without even talking by 2am the phone is letting me know the battery is low.
If I talk on the phone (under an hour) then the phone is dead by 11pm
I use Google Maps for the traffic, and I also have multiple exchange email accounts which check about every 10 minutes.
On days when I actually use the phone and google maps, if I unplug at 10am the phone is dead by 6pm.
At the moment I am running Schnaps 3.60a.

*All* PocketPC phones will have battery life about as long as yours has.
The problem here is merely that you are trying to compare its battery life to a normal cell phone. For the past 4-5 years, the battery life on Windows PocketPC phones has been about the same.
If you want to compare your PocketPC to another device with regard to battery life, you have to compare it to a laptop and not a cell phone.
Welcome to the future.
I do realize that all of the advanced features will use more juice. I use a HP iPAQ and a Dell Axim at work which both use WM5 and those only get around 4-5 hours of life before they are dead.
It just seems that battery technology is lagging behind the electronic gadgets that use them.
I almost hate leaving the house with the phone being less that fully charged in case I really need it somewhere I am not around a place it can be charged. Suppose a car charger would be in order.
Yes! Crappy Battery Life on the 8525
Yes. I came from an 8125 (ActiveSync on 25/7) and was able to use my phone for 1.5 days. With the 8525, I am lucky to get 6-8 hours. Big bummer!
I locked my 8525 into the Edge network and I believe that my battery life has increased marginally. Of course, this will not work for some people because they need the faster 3G network, but if you would rather have longer battery life, I say give this trick a try. It is really nice if you live in a fringe area where your phone bounces from Edge to 3G and back again frequently.

Sorry but you are totaly wrong.
I had a TyTN for 3 monthes. I hardly had more than 24h in standby (no phone, wifi & Co). Phone was only in GSM mode, no UMTS. Tryed a lot of rom/radios.
I sold it, cause this was really too ridiculous.
Now I own a HTC Touch. With same usage and applications installed, I charge my phone only every 4 to 5 days.
12h in standby = only 10% less for battery.
This added to form factor made me very happy, no way I come back to hermes or even kaiser ...
I picked up 2 Touch phones From Bell Canada and I have a question on the power consumption of the phones.
My wifes Phone has 80% battery left at the end of the day and mine has 30%. She has her phone almost stock with only 1 or 2 programs loaded and I loaded like 20 so far on mine.
She uses hers a little and I use mine well a little more then her, 20 minutes browsing plus 30 minutes of text entry, no phone calls on either.
I swapped batteries and the power consumption is the same on each phone.
Also when I played a golf game on mine the other day the phone heated up pretty good.( I might of had a few programs running in the background at the same time)
I am thinking that there might be a fault with my phone and I am hope other people can post there info:
Programs loaded/running Phone /Browsing usage Power consumed in a day
Have you tried hard resetting it and running it without your 20 programs to see if it makes a difference?
no not yet, I guess I could dump most of them and just leave the few I need, good idea, worth a try.
I have the same problem with my Bell Touch
The cause of the battery drain is the constant searching of phone signal reception.
So if you're in an area that you know has a poor Bell Reception, it better to turn off the phone function to save battery.
I live in a basement apartment and i found out that Bell has no reception in my place. one night i charge my Bell Touch at full battery before i sleep but i forgot to turn off my phone function, the next day when i checked it from 100% it went down to just 10%. i used to be with Telus before, and it the same thing very poor reception. but with Rogers in my HTC x7500 im still getting a good 2 bars of phone signal.
ok so today I spent most of the day outside, last night I dump many programs and turned the display down below halfway and I came home with 60%, so there was a differance, I think the biggest differance was the display being dimmer, still I got a 2200 milliamp battery and cover coming from ebay, should be here in a couple of weeks, I think it will be a must if you are active using the phone as a pda. ($15 delivered).

how much thicker does this make the device? how do you like the battery life now -- is it really 2X?
Is it just me or is it getting old with everyone CLAIMING "best battery life" when you usually end up with the same or worse than a stock HTC kernel?
I have tried NetArchy, KingKilck, and a few others only to have my phone die in the same amount of time or even sooner. Why is this? Well what you all don't do is take into account the MANY different variables that affect battery life.
The thing that tanks my battery the fastest is the fact that I work in places with low (10-30%) signal. This kills the battery because it is constantly searching for a signal and talking with the cell tower. I am willing to bet most people that have bad battery life are in low coverage areas. I simply have learned to put my phone into airplane mode and have people text me on Google Voice as I still have a WiFi connection. WiFi uses FAR less power then the cell radio in low signal areas and you can still maintain connections if you have everything setup right.
I am NOT in any way bashing the work and effort that has been put into these kernels but with the latest HTC kernels having unlocked FPS and great battery life why would I want to even mess with a custom kernel? The only reason I could see is for overclocking. I wouldn't even run one for underclocking as I have found this to NOT be an effective way to prolong battery.
Just thought this needed to be said. What I have said here also applies to collin_ph tweak. There have been many reports of the "tweak" killing the battery even faster and I have verified this.
Mostly true, but I think it really depend on what rom, and kernel you are using, plus your signal strengh.
I've flashed very often since the day I got the phone to get maximum battery life out of it, and netarchy's usually worked for me.
I've also tried stock/default that came with Myns 2.2, and best combination that worked for me are Myn's 2.2 and Netarchy's 4.2 cfs havs smartass more agressive kernel.
there are too many kernels out there and you just have to find a working combo that works for YOU at the end of the day buddy.
Oh and I totally agree with you on this thread that it does get annoying/frustrating to see these threads, and you decide to go with it, and it turns out to be a crap.
I've tried a lot of things and never really gotten better battery life than stock, but I have gotten about the same with better performance, which is good enough for me.
The only thing that really improved battery life for me was butchering the phone - turning off background data and auto-sync and using JuiceDefender (disable mobile data when the screen is off, turn it on for 1 minute every 15 mins). But I decided I prefer using my smartphone as a smartphone.
I've come to accept it. My average battery life on weekdays is 8-10 hours. I wish it were 12-14, but I can live with it. When I stay at home on weekends, where I have Wifi and good cell signal strength, I generally get 20-30 hours with moderate use.
I live with plugging my phone in at work, and I got some of tuttoit's cheap batteries off eBay. It works well enough for me.
Anytime you flash a custom kernel you have to give your cpu time to adjust to the new stuff included (havs,bfs,cfs,voltage...etc..)your battery life gets better days after using these new kernels not immediately after flashing...
i have flashed myn's 2.2 and using setcpu to underclock when in black out mode and using titanium backup to "freeze" apps that somehow start themselves. my batt life has gotten way better than what it was on stock os and settings. ive also tried to do the *#*#4636#*#* and cant get into testing mode to change from gsm to cdma but im willing to bet its on cdma anyway.

You can use Roam Control to force roaming in those areas, if they have good signal strength with another carrier.
It's the same power usage as in good signal strength Sprint areas.
im still trying to find the reason for my battery drain, i get an ok battery life with heavy use, but even at idle it varies, the other day battery stated 80% all day long, i ran it down as best as i could and got it to read 10% at 4:30 in the morning, i set it to charge, wake up, unplug it, go back to sleep, wake up only a few hours later to see that my battery reads 60%, im sure that nothing out of the ordinary was running, i cant seem to figure it out, and i have done 3 hard resets to try and find out whats draining the battery, seeing how it varies and is seemingly random at times, im starting to think it may be the radio
I would highly suggest buying a extended battery. I have complained about the battery since day one. Got the extended battery at sprint for $54. I went 8 full hours.. I mean 8 FULL hours hard usage. I turned the screen off 3 times. Wanted to see how the life would be since I used to be on my for for aboutt 3 hours and it die.. today tturned on phone at 9. Its almost two.. 93%.. I did have my brightness all the way up yesterday and overclocked at 113 on interactive.. tomorrow ill turn everything on and run it hard again.. ill turn my airwave off also. I will get worse reception than u would at work.. -115 to -120.. I hit -125 already but I heard -120 is no service..

Sorry but I like my evo to stay thin. X)
Same here.. but the extra thickness isn't really much a bother to me as much as charging and carrying 2 extra batteries. 6 hours now and at 75%.. I love it.. and glad I got it. Just hope when I get a different phone I can use my extending for it. Like I had tp2 and same batteries as the evo..

T-Mobile G2 Users Suddenly Suffering From Huge Battery Loss?
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
http://forum.cyanogenmod.com/topic/28386-excessive-battery-drain/
My drain is ridiculous. I'm traveling right now and I turned the phone on Saturday morning to use the navigation to get to the airport. 15 minutes later my battery was at 32% after being fully charged when I started. It is absolutely maddening. I can't go anywhere with my phone off the charger because it will be dead in 2 hours. I was thinking it was the battery and was going to start looking for one, but now I see it is more widespread than that. My buddy down here in Florida is having the same problem with his and he isn't a geek at all, so he'll never find these forums to find out what the problem is.
This is a major issue. I already restored a previous backup and still had the power drain. I reflashed CM7 and no change. No matter what I do it is killing my battery faster than it can charge. I'm tethered through wifi right now with it plugged into my computer and it is draining faster than it charges. At this rate it will be dead in 8 hours even though it has been charging the whole time. RIDICULOUS!
update: I did a force stop on Maps while it was plugged in and the battery actually started charging again. I just took it off the charger and we'll see how long it lasts. I do recall updating Maps maybe on Friday, so maybe that has something to do with it. That sucks too because I can't be without navigation while I'm traveling right now. Good thing I brought my car charger...
I had a 100% battery drain overnight. My phone was 100% charged when I went to sleep and dead when i woke up this morning. I did absolutely nothing on it except for a battery calibration then turn off the screen.

No drain here guys on RC1. The new maps has some problems, but no drain so far.

This is related to Tmobile's towers being upgraded. Turn off 3g/4g data and the battery will last longer, only toggle on data specifically when you need it and shut it back off. Ugly work around, i know, but it'll get you through until T mobile corrects the issue. It seems to be affecting other HTC phones too, they don't play nice with the new tower upgrades. This is a regional issue as some towers get upgraded before others.

Tap on the graph of your battery use. Is your "Awake" line solid? If so, your phone isn't sleeping and that could be your issue. It definitely could be some kind of radio issue with your device, sounds like that is common.

wow, i think your battery have problem, if you still keep it may cause harm for your device. You try another battery yet??? it may fix that
I don't think this is isolated to the G2, T-Mobile, or CM7. I think its solely related to Maps/Navigation, and maybe some hardware component of our phone.
I have a Desire Z, on AT&T, on Virtuous Unity, and I had a problem with this last Wednesday (July 27), the day the latest version was released. I was traveling, used Navigation, then didn't touch my phone overnight. I think the phone was pretty close to fully charged, and it dropped to stone cold dead in maybe 7 hours (or less, don't actually know when it died). I normally get great battery life, and have never seen drain anywhere close to this in the 8 months I've had this phone. Typically I get close to 48 hours on a single charge, with moderate use.
I hadn't seen this until today. I went to lunch with 80% battery, listening to podcasts in the car and reading google reader at the restaurant. I returned to 15% battery. A 5 minute trip away from my desk drained that to 0% and earned me an auto-shutdown just as I got back.
As for Maps, I got that update days ago and haven't seen any issues until just now, so I don't think that's it.

I did a complete wipe, reflashed my ROM, kernel (rmk v3), and radio and only had a 16% drop last night from 100%. I think it happened after I flashed UnityV4 kernel, so i guess ill see how this plays out.
My battery life has been a lot worse than usual lately, but I had no idea it was happening to so many people!
I was on Virtuous Unity v1.0 when it started for me last week. It drains from 100% to dead in ~6 hours while sitting unused overnight. Factory reset, wiped davlik and cache, removed Maps, got one charge use of 13.5 hours then back to dying in 6. Again wiped, loaded Unity 1.25 (haven't switched to DesireZ hboot yet), still dies in 6 hours. Only fix I and others have found on the T-Mobile support forums is switching to 2G data when not in use. Appears to be an issue with tower upgrades or something similar, someone on the TMo forums did a logcat and is seeing nonstop connect/reconnects to the network while phone is sitting in sleep and another mentioned they have a friend in engineering who said it's tied to the channel bonding feature TMo is implementing for data.
Supposedly an OTA or something is being worked on by TMo and HTC? Who knows? TMo CS is useless, still insists it's a battery or phone issue, and refuses to acknowledge anyone has ever even reported it (yet myself and at least 2 dozen others have posted on their own forums their experiences with CS attempting to report the issue). It's escalating to the point I'm going to leave TMo after 7+ years ahead of the merger decision...
I'm having the same issues, it just started a few days ago.
However I'm using in a Desire Z running Synergy RC 2.1 in Canada on Bell network. I normally get great batter life but all of a sudden it just started draining like mad and I'd be in powersave before lunch. I notice the refresh data icon is appearing a lot in the taskbar.
From the market comments, Maps 5.8 does have some sort of battery life impact, but I had it before the issue started and didn't notice.
I wonder if Bell is upgrading towers with this channel bonding feature for higher data speeds also? From the TMo forums it would be an issue for nearly all recent HTC phones that weren't specifically designed for HSPA+ 14mbps+ speeds (like the new Sensation from what I hear isn't having problems, but the MyTouch4G, 3G and Slide, along with Nexus One and others like the G2 do).
I have noticed lately that Maps is near constantly running in the battery stats list. Hopefully they fix it soon!
It's not Maps causing this problem (though Maps 5.8 it seems is causing some lag/higher battery usage for some users). I've reinstalled Maps 5.8, switched to 2G data only and already running over 16 hours with normal usage (switching to WiFi for some higher data usage browsing/downloading and watching some videos, otherwise using EDGE for emails and quick google searches, plus 4 phone calls and numerous texts and some Words with Friends - all background/GPS/sync data is turned on as well) and the battery is at 52% right now. Yesterday with 3G data turned on and Maps uninstalled the phone went from 100% to dead in 6h37m while sitting unused on a table. It's a network issue, at least for the majority of TMo users experiencing it.

I just turned off 3G/4G and opened alogcat.
The amount of log activity dropped like a rock.
Thanks.
Unfortunately it seems to be an issue that most G2 and other HTC phones that use the 3g/HSPA+ network in certain areas.
I am also having the battery drain problem where I was only getting less then 6 hours of standby time till my phone was dead.
Switched to 2g only mode today and still sitting at 100% with 2 hours off the charger a few quick calls and some txts and a little web browsing with wifi
Check the tmobile g2 support forums. I would link but don't have enough posts yet.
I've been having battery issues the past couple of days, too. I frequently bounce between MIUI and one of the Sense roms, so I thought it might be an issue with the latest MIUI build, but after looking at my battery stats and seeing the awake bar solid for 6 hours straight I realized something else was going on.
I have a G2, but both of my parents' phones have been experiencing battery issues the past couple of days as well. Mom has a myTouch 3g (the one that slides) and my Dad has a Sensation.
I had them use the *#*#4636#*#* menu to switch to GSM only, and they're supposed to let me know if that helps batterly life at the end of today.
I'm staying on WCDMA preferred, but connecting to my work wifi has resulted in a substantial decrease in battery drain.
My SIM card crapped out on me over the weekend. So I went down to a mall kiosk to get a new one for $10 (Bell wanted $30 btw).
After putting the new card in, I noticed last night that after having my phone plugged in for 30min it had charged significantly faster than what I have become accustom to. Now today is where I have really noticed my battery life. After about 8 hours on battery with light usage while at work (on wifi) i'm at 70%.. typically I'm down to 50-60% by this point in the day under the same conditions.
If watching Netflix on my phone while plugged in (using factory OnePlus charger) it would almost be slow and stagnant charging and I had figured it was just an aging battery. Nope, I now get good charging performance with screen on and streaming video.
Now I'm not conclusively saying that the SIM card was killing my battery life. But it is a HUGE coincidence. No other changes to my phone, no firmware updates, no app changes, just a swapped SIM card.
Might be better signal reception. I basically have none in my apartment and i can't get more than 5h screen on no matter how hard i try.
I'm just glad my battery has seemingly improved ~25%, the specs and more importantly daily performance of the One aren't all that dated and it doesn't feel sluggish when compared to a 6P.. I mean it's slower, but for a 2+ year old phone the improvements in the market haven't been that noticeably substantial..

Jup it has to do with that. If the signal is low the cellular modem needs more energy to hold that connection.
