I bought the Motorola Photon 4G in the U.S. but I live in Brazil. In the first 10 days of use it worked perfectly, had battery life of 36 hours with moderate use. After you update it to last OTA, I do not know if it was coincidence, the battery does not last more than 4 hours without any use. Already reset to factory rom, I used several methods to calibrate the battery, I installed another rom and everything remains the same. The screen and battery get very hot when using the photon. I bought new batteries and charger and nothing changed. The interesting is that even disconnected the battery completely discharges within hours. I use the minimum screen brightness, WiFi, GPS, bluetooth and data are off. Right now I have only the factory-installed app, and yet the battery only lasts about 4 hours. The Photon is not sold in Brazil, therefore, have no guarantee nor an authorized service center for Motorola Photon. From what I see must be a hardware problem, does anyone know what might be happening? (Sorry for bad english)
To be honest, I'm lost here BUT your comment about the screen and photon getting very hot, the only time I experience that is tethering and thats my last 3 devices. This is usually caused by rapid battery drain.
Although I only tethered a few times, the battery was, more or less, programmed, even after I stopped. I ended up buying 3 new batteries. Cannot remember where, but they were under $10.00USD (CellPhoneShop.com)
I definitely recommend you make sure your not tethered.
But have you tried a wipe/SBF?
If an SBF doesnt fix it its probably hardware.
Thanks for your help. But I find it very strange the battery discharges even when the device is off. Telephone operators in Brazil use GSM only, so the phone may be trying to find CDMA signal, but do not know how to avoid this.
Previously had installed the SBF "SUN-198_7" and nothing had changed. Now I installed another SBF (SUN-154_5) and despite the battery lasted a little more, still has low life. I'll try another SBF or other roms to see what happens. Then do I comment the result here.
After the sbf to 154-5 does the battery still get hot? This sounds like a bad battery. I'd try replacing it...lest we read about you on engadget or gizmodo in one of those exploding cell phone battery stories.
Have you looked at this thread yet?

After much searching, I discovered that the problem is hardware. I applied a SBF (SUN-198_6) to relock the bootloader and the root. I think it worked. I'll send for assistance technics, will they know that I unlock the bootloader and the root? Because if they find out, I lose the warranty.
I've had a major battery drain issue in the past which was due to a specific app that was just heating my phone up and somehow not jiving with the with the software (Widget Locker)... I disabled it and battery went back to normal. Also, since then the dev corrected the problem.
Did read several comments about the drop in battery life using the Widget Locker. However, in my case the battery is also drained with the device (Photon 4G) off. Even in Airplane mode the battery lasts a maximum of 5 hours without any use. I've tried everything, Factory Data Reset, other custom ROMS and even two other batteries, and nothing changed. I applied a SBF (SUN-198_6) to relock the bootloader and the root. I'll send for assistance technics, will they know that I unlock the bootloader and the root? Because if they find out, I lose the warranty. Will I have problems with this?
Also it sometimes helps to charge full and recalibrate the battery...good luck!
you might have overclocked your processor, try download setcpu and check bring it down to 1ghz, another problem might be dust inside the phone try taking out the battery and cleaning the inside of the photon with a dry paper towel
Hello, I`m new to this forum and wanted to ask if anyone knows why my HTC Legend drains battery so fast. My phone is rooted with Fuse ROM and unlocked bootloader but it was draining battery on stock ROM too. Even with the screen of it drains ( in 8 hours with screen off it drains almost 10%). I have 3G connection on all the time and when I`m at home i don`t have full signal in the house so it may be a network problem that affects the battery?
a weak network signal may be one reason for the battery drain (since your phone has to use more power to send data).
however when there's always synchronisation & exchange of background data going on in the background, i think 10% battery down in 8 hours isn't way out of the ordinary.
maybe you'll get some clue, what components are causing the drain when you go to settings > about phone > battery info...
Best solution to stop battery drain is turn every thing off if you're not using it eg GPS, wifi, Bluetooth, mobile data, auto sync, if you have them on they will chew up power.
On a stock legend, HTC would seam to have the CPU speeds set at 480 low and 600 for high, if you root and set your lower value to lower than 480 that will also help in cyanogen lowest value is 245.76, this seams to be ok, on other roms they can go as low as 19, this is not so good as phone can sometimes freeze. I never go below 122.

My HTC legend battery life is 2 days. But I enable internet access only when I want, same for gps
Have you tried to calibrate your battery after installing custom ROM? Try the free battery calibration app from the market.
I'm using "[ROM] B 0.8.4 based on stock HTC FroYo (04/13/2011)".
Using the stock speeds the battery drain is quite fast, I get a day at best. I'm running 245 - 804 and this makes the battery last days. I'll try down to 122 to get a tiny bit longer battery life

it is a common problem... as long as your phone signal is not dropping to completely zero that it goes for finding alternative networks its fine.. but if it is dropping blank .. try using airplane mode (ya no other option )
or else as a quick thing try below options
- try installing infolifes battery defender (tweak their ignore list if required). along with their advanced task killer (jst set for auto kill when screen off and not interval kill
- get a cpu governor (I was using cyanogenmod inbuilt one) and set in conservative a low-400mhz and high-600mhz
-turn off auto brightness if u've it on and use it in low as required
hope these should squeeze some more extra standby time..
I went back to a stock rom after putting up with the battery issues.
a friend told me that there's a .bat file that helps with the battery issue, but I haven't been able to find it anywhere.
I also had freezing problems when I tried to adjust CPU settings, so my best option was to bake a rom through modaco without all the bloat crap.
Now it works a treat.. hope this helps
Bat files are for windows computers, not used on android....
However your friend might be talking about the "battery.stats" file deleting it is supposed to help "calibrate" your battery, I personally have not seen any benefit to battery life doing this. Once your phone goes flat (turns off) and you then fully charge it it seams to set the calibration automatically. The only way I can see it actually helping if your a phone user that never let's the phone go flat enough to turn its self off.

IMO, battery life isn't bad on the HTC Legend if we compare it to High End phones. But there are ways to save it.
Ceebs typing the whole thing so I might as well link it to you from a similar topic: http://forum.xda-developers.com/showthread.php?t=1586022
Cheers ranger.
I asked him about it, and it was a .bat file that is used through the adb and he didn't say where he got his information.
Removing the battery stats file can be done with an app from the play store, and that wasn't anywhere near as effective as the move from cyanogen 7 back to the baked stock HTC rom.

Hi, I got a very annoying problem.
Since a few weeks ago, flashed a ROM and when I've tried to use the phone, it keeps turning off randomly, sometimes after a few minutes, sometimes after hours. So, I tried to take it back to the clean original 2.3.3 ROM, but it keeps happening. ¿Any idea? ¿Any solution? Please, help me.
Oh, something else, it only happens when the phone's used with the battery, when it's attached to my laptop and used as modem, the problem doesn't appear.
I had the same problem, it said android system shutting down. I just bought new battery and it works.

I think, it's the most logical option, but I was trying to get some feedback first. Thanks.
Maybe calibrating the battery.

go back to stock and see if it helps! try to troubleshoot the problem! Also, don't install any apps!
There are instructions on how to calibrate your battery in the first post in this thread:
http://forum.xda-developers.com/showthread.php?t=1489214&highlight=calibrate+battery
If the problem is the battery, you might find that after calibration that the battery drains faster than expected, and still shuts down, only this time it warns you that it's gonna shut down. This would then be the true battery drain. If that is the case, you might just need to buy a new one anaway.
Otherwise, I don't know what else could be causing those symptoms. (Other than an electrical fault, from accumulated damp or something)

thanks so much..............
What happens it's that the phone shuts down suddenly, the message appears for a seconds and it's off. Wait for a few seconds, try to turning on again and sometimes works for some minutes, and sometimes it's keeping turning off, and off, and off. But, the battery level seems to be correct, I mean, when I turn on the phone after one of these sudden shutdowns, only drains the logical ammount of battery for starting use the phone.
I think... if the problem never appears when it's attached to the laptop and charging constantly, and magically appears when I used the phone with the battery, it's probably just a battery issue, right?
I have a similar problem to this, my phone randomly shuts down after showing the 'Android System shutting down' message but sometimes loses ALOT of battery. Last night it went from 78% to 8% after shutting down :/ I noticed it happened more often when im playing games or taking a video, things that take up more battery. When i keep it plugged in it keeps awake so the problem stops but i cant keep it in all day every day. I dont really want to buy a new battery until i really really have to, but I have had the phone and battery since the x10 first came out about 2 years ago, so anyone any other ideas? Thanks

Try wiping battery stats then charge to 100% (it may help, not sure)

Yeah tried that but it didnt seem to work :/
could it be hardware problem like broke battery or bad connection on motherboard?
Could be pal are u within your warranty (sony (Ericsson) it has a 2 year global warranty but u need to ring ur network provider and ask them to put u through to se
Sent from my X10S using XDA
Yeah this happened to me before about 6 months ago, so i went to my provider (3) and they sent it away to Sony Ericsson and they sent me a whole new phone but I didnt want to do that again really, but i may have to. When im not using WiFi or 3G then it works fine, and when its plugged in to the charger it works so i guess its a case of not usuing the internet when im not near a charger
I have the same problem.
My X10 reboot random when using 3G (Wifi is still OK) and Gaming. Now i'm on Stock 2.3 and stock kernel and....wait. (Flash some ROM and change the new battery....but not solved )
Anyone help us !!! Plizzzzzzzzzzz
Maybe your solution
I had the same problem sometimes with original kernel after 1 year of using my phone.
Then i tried to install a new rom, and i was thinking the problem was solved. But it was not...
I finished by trying the X10S (v7) rom with DoomLord kernel (1113mhz) and this problem was solved...
I tried some kernels and this one was stable with a good battery life and no shutdown problem. With some other kernels i had this problem back.
So I think that kernel could be the problem.
Infortunately, with the rom X10S v8, Doomlord kernel cause issues with wifi (unable to get ip adress). So now i use kCernel-SE-stock-mod-v1 and no shutdown problem anymore.
*Maybe the solution is*
Try to change your kernel with one of thoose :
- kCernel here (in "2. kCernel-SE-stock-mod-v1")
- DoomLord (search fo x10_gb_DooMKernel-v06-1113_wifi.zip)
Note :
- With this two kernels, you'll have to download appropriate wifi patch and install it from SDcard via xRecovery
- don't try to install X10S v8 if your bootloader is locked
So, try to flash your X10 using flashtool with Doomlord kernel
Tell us if it worked, i hope it solved your problem as it do it for me.
voltage
Hi,
I have had this issue too, for the last few months. No matter what ROM/Kernel, batt stats cleared, etc, still the same. Can idle all day, but as soon as I use 3G, GPS, or use any intensive app, she shuts down.
As an experiment I installed a battery monitor that plots graphs of % charge, temp, voltage, etc over time.
I had a close look at my logged graphs and have noticed that just before each reboot, the voltage seems to dip drastically. Battery charge is fine, does not seem to matter. but a sharp drop in voltage occurs. Increased draw for the more complex tasks (3G, GPS, etc) seems to be tripping it up.
As the Battery is now 2 years old, I figured it is just starting to fail? And iv noticed lots of people are suddenly coming out and complaining about this issue.
I just ordered a few new Batteries from 'Ebay', will see how we go!...
peace.
[INFO / SOLUTION] Suddenly shuts off with red LED.
Good to know:
The X10i/a have now reached an age, where battery failures is very common nowadays. Specially if one got the device early on or just after the launch.
Symptoms of a failing battery:
* Device suddenly shuts off, even when the battery have several percent remaining.
* Device drains fast, even when not used.
* Device might just shut off for no whatsoever reason when doing something that draws a lot of power, and will restart just fine.
* Device has a surprisingly fast charge time from empty to full.
When the device shuts off all of a sudden, it's followed by the indicator LED blinking red, rapidly three times, and might repeat this at restart attempts.
Sometimes it takes several tries before the device starts up again. Battery just needed a few minutes/an hour of "rest".
There's nothing wrong with the device.
Just get a fresh replacement battery and it'll work just fine again.
But beware:
There are many fake batteries out on the market, claiming that they have higher capacity, yet very slim in size.
There's a simple rule when it comes to battery capacity:
More capacity = larger in size, which might need a special back-cover. There's no escape from that.
If one would happen to find a such incredible slim battery with super capacity, the battery security circuits and/or chemical makeup probably have been circumvented/changed, and have a high risk of catching fire and/or explode when charging/discharging.
Yeah thanks for all the advice and sharing your problems. My phone does reboot alot when im using 3G or taking a video. Recently my battery would reboot, drop alot of percentage and then increase percentage without charging...magic I dont really want to buy a new battery because my new contract starts in june i think, but maybe il have to. Good luck for everyone else dolving there problems
Also, [email protected], i am on doom kernel and i still get reboots :/

I've too had the same problem. solved it by replacing battery
Now everything's alright
I'm running dixperia rom with stock kernel
EDIT: but now I have a small problem. Hope someone can solve it. Sometimes, suddenly, the hardware keys light and backlight turns on, without doing any thing and this drains my battery I have to turn on the screen and turn it off back to switch off that backlight and hw keys light

Im getting a new battery soon I hope so I will hopefully get my problem solved
Hi there folks, yes i'm noob, i tried to search for a similar situation but i would apreciate another opinion since i'm observing my phone and i can't understand at all. Everything started when i was on 4.0.3 stock branded and my batteriy suffered of instant drain, random reebot and stuff, i decided to move to Cyano9 but the situation was the same and so here i am on a 4.0.3 stock italian after a deep clean. The problems persist and it's get annoying. i noticed that the phone shut down mostly when i'm using it (browsing internet, downloading stuff..), in the last few hours twice while downloading from play store, and once when playing a game, and after the shut down i have problems in restarting it; when i manage to power on (sometimes recharger is needed) the battery ha 30/40/50% lower charge. First I think it was a rom problem (cyano9), but now problems won't end, the fact that the phone reboot when i'm using it does indicate that there is still a software problem or maybe it's just the battery that can't handle anymore? i have this phone since last year and previously I've noticed a general lower charge. I hope it's not an "internal" problem, i can buy another battery, but not another phone! I've tried to recalibrate several times, two or tree time waiting for total loss of percentage and recharging it for 4 hours, using recalibration tool from Google play, as i recall a wipe battery... from clockwork, but now my cell is not rooted.

Hey guys! I want some advice to check if this problem is normal or maybe its a manufacturer defect.
Anyway, I bought this phone about 5 days ago, and in the time I've been using it, my battery lasts about 7 or 6 hours (also it takes like 5 hours to fully charge it, which makes it worse). I thought it was because the stock ROM isn't very optimized, but later I started using cm 12.1 and it seems to last almost the same. Also, I started using an app called "current widget" that checks continuosly some info like the mA that is using at the moment, and I found that when I use it, it's mA is between 500 and 600, and sometimes it's like 180. Is this normal?
I'm worried because I've read in reviews that the battery of this phone lasts about a day and half and mine barely lasts 7 hours. Please, help...
Mine will last for 2-3 days if left alone. I'd download an app or CPU monitor to see what's running and draining the battery.
I repaired it already ^^ I just flashed official firmware again and no more battery draining and heating.
Battery draining could be many things but usually comes down to rogue processes.
Since android is java based over C, it becomes a garbage collector. Be sure to clean your device frequently to avoid internal confusion.
If a simple cleanup doesn't work, you can try to remove processes from loading at boot.
I honestly think that a reflash of your ROM is a bit extreme for a battery draining problem. I would try to exhaust every other avenue first.
I know, but I even tried disabling apps and it stayed like that. Also I flashed other roms and the problem didn't stop. I was going to claim my warranty and that's why I flashed everything again and somehow that solved it. I suppose my carrier modified the software somehow and that's why my phone had that problem.
Put your phone in airplane mode when you aren't using it. See if the battery drain persists. How is your signal? If your phone has a low signal, it will actually boost its radiation to try and keep the signal or establish a stronger one. This only is a battery killer and an issue that cannot be fixed by any software/firmware update that I've ever heard of.
If what I suggest seems to be true, airplane mode will be your friend. Or at least turn off data while not using it.
Good luck!
