Ok, my battery is weird it doesnt last long. it dropped from abut 95% to 70% over night, with checking email every 30 minutes with k9 and the mail app every 4 hours. My phone doesn't last very long either, I haven't tested it fully. I always keep charging it, when im in the house.
I bought it from T-Mobile and i could swap it. Should I?

Might be worth it, I have Friendstream updating default setting, Googlemail (although it's push) on at all times, browsing a fair bit (on mobile net and WiFi) and a few calls and it last 2 days-ish...I'm using a generic Desire on latest FW
Mine's the same. I didn't think it would be worse than my old BB Bold for battery life, but it really is very poor. I don't think you have a fault, it's just the way it is.
I wondered about closing background apps but I've read that having them open doesn't impact battery life. I do have a few background things going on though that will affect it, so maybe I need to consider if I really need them or not (frequent email syncing, contacts/calendar syncs, etc.).

Have you put the phone down for long periods in-between uses, or have you spent a fair time writing emails or just playing with it? I've spent a fair time on mine but not constantly, and no more than I used to with my BB Bold. I used to writing emails constantly on my Bold and the battery would last a good day, but until I'm used to this keyboard I won't be doing that on my Desire.
So It won't make a difference if i swap it? I also didn't do the standard charge at the start. Couldn't resist playing with it. So It was on charge while playing with it. Could that make a difference?
I'm in work a lot and I'm not constantly on it - just check for emails/SMSs every hour or so so prob spends a lot of the time in standby. I'm on it more on the weekends but it still lasts well into day 2

If it works otherwise then I doubt there is a fault that would cause the battery to run down but nothing else not to work.
Not charging the battery at the start is one of those things that some say makes a difference, other say it doesn't. With Lithium-Ion batteries I always thought they didn't need that initial charge, but I can't say for sure. Anyway, what might help is if you did a full charge then a complete discharge (use it until the phone turns off) then a full charge again. With older batteries at least, that tended to help them last longer.
There a a few threads on this alread here and on the Android Forums.
There is a problem where the phone when charged left on, only goes upto 98%. However the phone will soon drop to 90% and lower quickly, indicating the phone has not charged properly.
If you unplug and reconnect, it will go back to 100% but almost as quick as tying your laces, it will go from 100 to 98% and continue to drop.
It could be faulty batteries.
I was hoping the FW update would fix but it hasn't as I found out last nite.
Or should I just buy another battery?
I've been having similar issues,
I get much much better battery life without mobile networks on, and alot of application crashes/phone reboots to get it work like I expected.
Took some data:
1hr of phone in sleep mode w/ mobile internet on = 4% battery
1hr of phone in sleep mode w/out mob internet on = >1% battery
So I can get a good two days if I don't have any internet with moderate use, but about 16 hours with internet always on and moderate usage. If I really 'rag' it and use alot, I can get about 50% done in a few hours (not constant use either, just alot of google goggles mainly!)
This coupled with the crashes and reboot made me get an exchange, I'm just hoping it's better, and really hoping its not worse..
Wish me luck, I wish you all the same.
After couple weeks my original battery seems to last longer - I do with 1,5 days now (with some browsing, 3G, occasional GPS and bluetooth, weather & gmail sync, dl apps from market etc). So it might be true that after the initial couple weeks of usage and charging the battery performs much better.
Intrestingly T-Mobile promised to send me a new battery over a week ago. As it never arrived I called them and was told they dont have any... but they would credit my account with £20 to buy one. Today... I received an extra battery from T-Mobile!!! No idea what is going on - and if I still have that £20 credit in my account
I will give that new battery a loooong first charge, see if it helps.
what about the 3000 mAH batteries?
Are they any good and would it work for the Desire?

Won't help, once it's at 100% the charging will stop. There is no such thing as 'long charging' li-ion batteries or 'trickle charge' a li-ion battery.
You can try to do a full first charge (until the green light burns) and then fully discharge (until the phone goes off). Then fully charge again. This will calibrate the battery chip and make sure you see the correct percentage.
If battery life is still no good then it's because you use the phone too much. Read: constant weather updates, friendstream updates, push mail and other stuff that constantly use the mobile connection. Also turn off gps unless you need it.
Turning off those services and turning off the 'always on mobile connection' can double your battery life (read: standby time).
It's not something magical, it's completely normal. If you want the phone to do a lot, it will obviously use a lot of battery.
Just for the sake of it, put the phone in airplane mode. You will be amazed how long it will last.
It's the main problem with modern mobile devices. Battery usage and capacity are no longer in good balance. What we need is more compact batteries that have more capacity.
At the moment it's clearly a comprimise between battery size (thus capacity) and battery usage. It's up to you to see how much you want to comprimise.
And so far, with every HTC phone, after a few (radio rom) updates battery life increased.
And... what everyone seems to forget, when you first get your phone you will fiddle with it.. a lot.. And once you have it for like a week or two, you start using it differently. Usually ending up with better battery life!
Try to run it down to around 5-10% after each full charge, but don't let it go completely dead if you can avoid it. Do this a few times and you will notice an improvement. Plus of course, when the novelty wears off and you use it less the same will happen.
Back when I got my Touch HD it would only just last a day, but by the time I was on the upgrade path I could get 3 or 4 days out of it!
Just to confirm, I was a bit worried at first about the battery life of the Desire. The first 2 days I could only manage to get 7 / 8 hours out of it. When I turned data sync off at night, it still lost 40% of the battery .. doing absolutely nothing.
However as mentioned before, I'm now on day 6 and now I can easily get 36 hours of browsing / texting / calling 2 hours + / even playing occasionally games. At night, without data sync, it drops just 4%.
So if you're worried about your newly acquired Desire's battery sucks, It really needs some calibration. After a few days it'll work as you wish.
T-mob battery
Hmmm.. Not sure what T-mob is up to. They promised me a £20 credit to by a battery (they didnt have any in stock) then I received the battery in post. I called 150 and they confirmed the £20 credit is still there for the next bill...
I couldnt be happier with T-Mob! Besides this I got 100txt/100min, plus 60 min included to Eurasia, Internet and 40 free txt to Europe = all for £10 a month!
Now I just need a case for it... waiting for the PdAir one to come, had one for my Compact IV and loved it. Its the flip one that opens upwards not down, so wont mess with the hardware buttons.

I really hope that's the case...
I got my Desire on Tuesday, first use was on Wednesday.
Yesterday (Friday) I put the Desire into Airplane Mode - I deactived everything. Turned off WLAN, mobile Internet, Syncing off manually before I went into that mode, just to be sure. When I went to bed, I had 72% battery left. When I woke up...50%...seriously, what the f...?!?!
8 hours of doing absolutely nothing uses 22% battery?! It's really annoying at the moment, absoluetly unusuable unless I'm home and know I can plug it in any second. When I'm out, I don't even dare to use mobile Internet, because even without it it only lasts till I get home (no WLAN, no mobile internet, just using it as a "telephone"...).

You expect the phone to stay turned on without using any power? This isn't a dumb phone, it is running powerful components and 8 hours doing "nothing" is relatively long time and the power usage of keeping those components powered at idle levels is going to add up no matter what. If you can't bear to turn the phone off if you can't control your usage, carry a charger or battery you should have got a dumb phone.
Bear in mind that the full capacity of the battery won't be reached until several charge/discharge cycles have been done, especially when you are using the battery for the first time on a new phone or on a phone with updated firmware. I noticed this while flashing custom ROMs on a previous handset. I'm sure we will also notice improved battery performance when firmware updates become available.

When the battery life of a phone like this goes bad is it a sudden thing? Or does it gradually hold less charge?
I've been using this phone for the best part of 16months with excellent battery life lasting a week with little use. Now all of a sudden it dies EVERY day when I've charged it the night before.
It doesn't even make it through a day at work if I don't even use it at all. No texting, phoning email or anything and it still dies fast.
It can be sat in my pocket all day and then I come to look at it at 6pm and it's off because the battery ran out again
This normal when the batteries start getting a bit old? I thought it would be more gradual, literally 3 days ago it went like this over night.
Anyone else have this problem?
check power settings to see if your auto backlight/power off settings haven't magically been disabled.
Had the exact same problem. Have followed all suggestions available-
making sure wif-fi/bluetooth off
Applications off
internet optimised
battery left to drain, phone reset and new battery fully charged before turnign back on
and several other procedures. 3 new batterys tried including 1 200o battery.
No luck with anything. i get about 6 hours if i dont keep toppoing up. Have to carry a spare battery everywhere.
Has anyone any solutions!!!!????????????
If you are having the issue even with a brand new battery I'm going to guess something's gone wrong with your device.

Not necessarily.
2OP - did you do a hard reset ? If not, do that, do not load any applications, do not change any settings other than the ActiveSync "fake server" trick (which assume you did already), and see if you still have a problem.

For 16months, i think you made the best of your battery life, i think it would be best to replace it as after 400 charge cycles, the battery deteriorates
One other thing I've noticed is that when the battery does run out, the clock has to be re-setup every time. I never had to do this when my phone ran out before. I'm wondering if this is indicative of a probelm other than just a shabby battery.
Thanks,

My tilt 2 had the USB problem (where it (seemingly) charges fine, but it cannot sync).
I noticed that the battery that could go for 2 days with very light use, would not go through more than 1/2 a day even when I don't even touch the phone.
I woud try to plug the phone into a computer via a USB cable and see if the computer recognizes the device.
My phone was under warranty, so when the replacement came, I put in the "dead" battery (according to my defective tilt2), and it listed 70% on the replacement phone.
Anyway, it does sound like you are having the same problem, because you have tried new batteries. So if you try syncing with USB and see if you have the same problem.
All, I seem to be having the same issue with a Sprint TP2. I had the first one replaced thinking it was the device. The replacement arrived and had the same issue. I took it into one of there stores and had the battery replaced. No dice. The battery drains 10% of it's power every 20 minutes, that is with nothing running and me not messing with it. I tried different ROM's thinking that would help. I installed NRG Dinik, GrooveROM, NEO_cht 2018, and Ana CHT. The issue still remains. Yesterday I came across a thread suggesting that I drain the battery completely, the recharge for 5 minutes, powering on and then clearing the storage(Hard reset while the phone is on). Phone charge seemed a little stable in the morning for the first hour, then returned to it's annoying 10% drain every 20 minutes. Any other suggestions?
Left out this folowing information, thought it might be relevant. Also had my charger replaced. Another thing I noticed with this behavior is that the contacts duplicate themselves every so often...
Go to Settings > Sound & Display. Check that the following are turned off:
Quiet ring on pickup
Pocket Mode
I played around with these for awhile and found that either of them, when turned on, will kill the battery in just a few hours.
Also, if you have a Hotmail account set up on it, make sure that it is not set to synchronize "as items arrive." Although you can get away with this setting for Exchange, Hotmail will kill the battery as fast as the above two settings.
3G Search Causes Battery Degradation
Hi,
I wonder if this might help? Maybe I am too late on this. But I recently was having trouble with the very same sudden poor battery issue after using my HTC Rhodium for more than a year with excellent battery life. At the same time I noticed that I was having trouble staying on my cell phone network, also suddenly. This had not been a problem before. Reading the forums in another area discussing signal issues someone pointed to the existence of "CMBandSwitch.exe" which lives in the Windows folder on a standard ROM. When you run this you can switch from "Auto" mode where the phone polls all available network bands and instead have the phone work only on the GSM band. You can also specify your frequency if you wish. When I did this I solved both problems at the same time. My phone once again was able to hold the network just fine and my battery life returned to normal.
I am in Europe on an extended assignment and I can only think that the local network is undergoing some changes that has their 3G signal weak which was causing my phone to work harder at staying attached and therefore creating both poor connectivity and poor battery life.
I hope this will help you.
.Hello everyone,
Just got my G3 about 3 days ago, and so far the battery is going really bad for me.THis phone would consume the whole battery in just 6.5 hrs!!
I used to have Xiaomi Mi4 before it and it would easily make it the whole day -some times +18hr- on the same usage connections.
I've tried different roms and kernels, limited the CPU to 1.9GHz, set governor to powersave, set brightness to auto and then to 30% manual, and still all the same, nothing better! I don't play games or use huge apps, just facebook, whatsapp, 9chat, calls, and FaucClock.
On average, I lose +10% of the battery per hour, Is this normal for this device? The battery says it's 3000mAh but it's acting like it's 1450mAh!
UPDATE:
Yesterday I tried to drain the battery to 0% to charge it again by watching a Full HD movie. It consumed about 30% of the battery leaving me with 30%, that was on 02:48AM. Today I woke up at 9:00AM and there was 29% left, meaning it only consumed 1% in about 6hrs. using the phone would consume more than 5%/hr but the standby is getting really good and very stable. I'll be draining the battery and try to recharge it later hopefully it can get better than this.

Thanks for the reply. I really don't know how to read it, so I just attached some pics, I hope they're useful for you.
I have the same, if not worse, battery drainage. I got my phone(new) yesterday. Just 40 minute ago o was charging it and after i plugged out o saw immediately how the battery was draining more like a % per minute . I looked in the the battery section to see that it'll stay on for 3 hours and 40 minutes. Now i'm letting it play on YouTube till the battery is empty-empty , do a recharge and if that is not the case, maybe i just have a faulty battery and hopefully not a faulty phone. Although i looked at the apps that were used in stand-by(over night) and i sow that Google services was using 16% battery in stand-by , something that i never had like that. Yesterday when my phone arrived it had already pre installed Lollipop 5.0 . After connecting to wi-fi the software updated once more with a small file, something like 120-160 mb, i'm not sure exactly. Now it says that it has the latest update - 20h . I'l do a few full discharge/charge cycles and if that doesn't solve the issue it must be the battery or the phone. Either way i hope i'll not end up returning the phone for testing , the though is already infuriating me a little.

I just hope it's the first few days of the battery life and it would get better by time, but tbh this is the first time I see something like this!
I don't know if it helps but I had similar battery drain after I install a new update of Android. It happened after every update.
For me the solution was a full wipe.
After it I can reach ~2days with ~4hours SOT.

At the time i posted here(post #4) my battery was at around 60 percent playing YouTube for the first real drainage of battery science i've got my phone. Now it's at 12 % with 26 minutes estimated till complete drain. I mention i have the speaker on mute. If i had it on the drainage would've been a little faster. Anyway, after the drain i'll recharge the battery and let it overnight in stand by with the wi-fi on. Also the location will be enabled so the data connection even though it's somewhat deactivated by the wi-fi on status. I enabled also bluetooth and NFC although those are more dormant than active. It'll be setted just as i'm using it daily . Now it's 12:14 AM Eastern Europe time. I'll post here the finishing time of charging/letting it in stand by. In the morning (my morning time ) I'll post again the battery percent. I'll use the phone normally with a little bit of everything . Wi-fi will be on all the time, so the voice network and from time to time i'll "simulate" a carrier 4g/LTE data only usage(YouTube, FaceBook and Mail). I'll post againt the time when the battery will be depleted completely.
It's now 01:12 and the battery is empty. I'll charge it and talk to you in the morning.
Check the SD card. do you still have a battry drain if the sd card is in the Phone?
i had the same problem. i toke the sd card out and my Phone was normal again and no overheated Phone.
i formatted my card to NTFS and it worked.

I don't have an SD card.
You have stock firmware?? And try to install os monitor and it tells you witch program is using the most!
On stock rooted firmware
I also don't have an sd card, and of course i did a phone reset before recharging. I'm getting a little worried dough. Last night it finished charging after 1 hour and 50 minutes. I immediately started tu setup the phone with the google account , did a google restore . Also i forgot to tell that i'm on Orange Romania and i do have some bloatware but i disabled all of it just to make sure that those apps won't interfere with my test. Already my battery was at 85% before going to sleep. I mention that my google restore does not take to much time . When i woke up 10.45 AM my time( now is 11.23 AM) the battery was at 75 percent. I stayed a little on YouTube and just answered a 30 second call and it's down to 67 % now. I am getting aggravated. I'll call Orange support to tell the about the situation and i'll ask them if i can firstly try to fix my problem alone by rooting the phone. If they don't like the idea of rooting my phone i'll try a few more charges/discharges .
Install OS monitor!
I'll try it. Thanks! By the way now the time is 15:56 and the battery is at 66%. So it lost 2 percent in 4 and a half hours(stand-by).
Ps: now that i woke it up for writing this post, it's at 63%.
I have a 2 year old S4 Mini (GT19195), currently running latest stable CM 13.
The phone is working fine except for the occasional (once a week or 2) unexplained battery drain.
With my fairly light daily use, the battery is lasting over 2 days. <And can usually run 4 or more hours screen on.> However, in the last few months, at random times (even with phone asleep - screen off for > 10 min, so presumably in doze), the phone will heat up, and battery will drop 5-10% per minute. After the phone shuts off from dead battery, recharging and restarting the phone will return things to normal, until the next time.
During these episodes, the phone behaved normally, I did not notice any lag on waking up the phone, switching/opening apps, etc. The battery meter page showed no unusual process using the battery (none of the process actually showed any increase in % battery use); except for the battery life dropping off a cliff as I watch. <I noted that the battery usage stat never adds up to 100% even in normal use ... It might show 10% screen, 5% Android, etc, but all that only adds up to 50% or so from full charge to when the battery is near dead.>
Anyone seen this before? Is this a sign of an ailing battery, or something else? Can this be a software problem - like something running away in the background? <Of note is that this happened once when I had completely wiped the phone and had the fresh install of CM 13 + Gapps (micro) ... so if this is software, it would be something in stock Android, rather than a 3rd party app.>
Thanks for reading & responding.
@JohnSoong
This sounds like the processor is stuck on max frequency. Either it is an app(s) playing up or some other process that is keeping the CPU working when it should sleep.
The first thing I would do is install BetterBatteryStats app or something similar to see what is keeping the device awake. You could also try to grab a logcat, but you would need to catch the incident and either plug into a pc with adb or run an app like catlog

The phone is working fine except for the occasional (once a week or 2) unexplained battery drain.
With my fairly light daily use, the battery is lasting over 2 days. <And can usually run 4 or more hours screen on.> However, in the last few months, at random times (even with phone asleep - screen off for > 10 min, so presumably in doze), the phone will heat up, and battery will drop 5-10% per minute. After the phone shuts off from dead battery, recharging and restarting the phone will return things to normal, until the next time.
During these episodes, the phone behaved normally, I did not notice any lag on waking up the phone, switching/opening apps, etc. The battery meter page showed no unusual process using the battery (none of the process actually showed any increase in % battery use); except for the battery life dropping off a cliff as I watch. <I noted that the battery usage stat never adds up to 100% even in normal use ... It might show 10% screen, 5% Android, etc, but all that only adds up to 50% or so from full charge to when the battery is near dead.>
Anyone seen this before? Is this a sign of an ailing battery, or something else? Can this be a software problem - like something running away in the background? <Of note is that this happened once when I had completely wiped the phone and had the fresh install of CM 13 + Gapps (micro) ... so if this is software, it would be something in stock Android, rather than a 3rd party app.>
Thanks for reading & responding.

That sounds like an issue I've had for several months, also running CM13 (Official) nightlies & Open GApps micro, unfortunately I've never had the time investigate (well I did once but it worked fine, I couldn't recreate the problem). It is currently happening less than once a week so not a major issue for me.
I've noticed several times that the phone felt hot, I've then used the Trepn profiler app, it would show the web browser running at 30-50% cpu constantly, so stuck as per @noppy22, though not at 100%. I have tried all the major browsers and they have all done it at some point, also most have crashed at some point, which I suspect may be related. Normally just the browser app crashed but yesterday using Chrome the phone FC and rebooted itself. Crashes seem to happen when I touch screen or scroll (though one may not have been when touching). Also XDA app crashed (1st time) when scrolling a couple of weeks ago, so probably not just browser issue on some sites as I thought previously, but might be unrelated. The stock battery meter did not show particularly high battery usage by browsers, though were a little elevated in % terms but hard to tell due to different usage patterns and not checking when things are good! I have noticed a bit of lag, which now makes we run trepn, if it shows high than expected usage by an app I close the app, which fixes it even if I go back to the same web page. This morning I woke up and my phone was off, I put it in my night-time profile (wifi & data off) that normally only uses a few % overnight but last night it must have used more than 30% of battery that was left, first time this has happened.
The other thing to consider is how good is your battery? At 2yrs old it could be tired if it's had a hard life (though yours maybe not) or you have allowed it to get very hot eg I did one trip using gps nav with phone mounted in windscreen cradle driving direct into the Aussie sun when my battery was about 2.5yrs old, thinking back I now think this was when I first noticed my battery was really dropping of quickly when around ~40% charge (though it was faster with more charge remaining also than my new battery, I would say), so think I the high temp the phone got to that day affected the battery. I think 4hrs of screen on time may be marginal, I was only getting about 3 to 3.5 when my battery dropped off fast, my new battery is giving me 6hrs SOT (mostly using browser app), so possibly you just need a new battery as only one other user has reported high cpu usage like I have.
Battery stats not adding up to 100% is normal.
I've just installed BetterBatteryStats, so I'll give it a week of so and see if it catches anything. So far nothing unusual in the stats.
I am leaning towards this being a hardware issue, likely the battery. Since the phone responded fairly normally during the overheat & battery drain episodes, this does not seem to me an app taking over the CPU. If the CPU was occupied by an app, shouldn't everything else be slowed down?
I have so far noticed no particular pattern to these episodes, and I cannot reproduce it at will. It is infrequent enough for now that I can live with it (although an unexpected dead battery is annoying.) I will see if the monitoring app pick up anything.
Hey guys,
Maybe you have to try to flash your stock or custom kernel again.
Thats probably the problem.

When I got mine a few years ago the media process kept getting stuck and overheating/draining my phone and even a reboot wouldnt fix it. I found out because I was using the system panel app and monitoring cpu of system processes. I ditched and deleted the gallery app (it was trying to create thumbnails for 100+gb of photos and videos) for quick pic v.4.5.2 on every phone I've used ever since and haven't look back.
So about a month ago, I used to get about 40hrs of battery life with a single charge. Also, the overnight drain was about 3-5%. This was great and normal.
Suddenly, it's been a month since my phone drains like crazy. 20-25% overnight drain, and an always steep slope down battery plot. In fact, the plot indicates no flat regions. I'm sure it is not a third party application that's draining my battery, as the issue persists even right after a full factory reset.
I have attached two figures, one for the battery and for from the Naptime application that shows the doze times and supposedly blocks wake-locks. Still, huge drain. These figures are taken 9 hours after a fresh factory reset, with nothing new installed on the phone expect Naptime.
I've looked so many places and tried many different things. Can someone help me understand what's going on? I'm running N950U1EUE3BRA5 firmware if that makes any difference.

Well since introduced out tablets have had to do power resets time to time to clear battery data. It's been an ongoing issue since Kit Kat upgrades from JB.
Since your device is 3 years old now, i assume the battery is bad. Very few have their original battery. I suggest checking on ebay, or dispute the transaction in that the item is not as described. Does not hold charge. You should get your money back. PS your 3 year old Note 8.0 should only be $50 at most. I got my new AT &T version new back when for $150 no contract no service, and my wifi variant for the same $150 US shipped about 6 months after release.
