Can't Believe my Touch Pro Battery Backup

Well, I am not complaining. I am surprised and I am here to share with you all my battery backup.
I have last charged my phone 4 days back and I still have half of that green bar left.
Its been some 8 months or more that I am using my phone and the battery backup never lasted more than a Day. I use to charge every night and the battery use to drop to less than 25% by the late night. I didn't panic though. I use to read about others experience on the battery backup and given the features and usefulness of the phone, i have no regrets what so ever.
I didnt upgrade anything on my phone including the ROM,
But I am quite surprised that its been 4days that I last charged and the battery is still at 50% and my usage didn't change a bit.
Am I going to get the backup that the HTC spec talks about?
Guess what? my GPRS is not working for some reason since a week now and i believe that is helping the battery. When the GPRS was working, it always use to be on air and even if I disconnect, it reconnects and stays that way because of automatic email checking.
But if it is really the GPRS, how do i live without that when the device itself is build for messaging and emailing? How do I optimize this?
What do you think ?

What "battery backup" are you using? Is this an external battery pack that you plug in?

No stevens, i am using the default battery that came with the HTC.
By saying Battery backup, i mean the standby time.

In diamond tweak you can choose to disconnect your data connection after not using it for 10 sec. through to 10 min. Try this, works just fine on my TP.

pointless thread please delete
of course the battery lasts if the radio is turned off

Automatic email checking uses a LOT of power so it is not wonder your battery lasts longer when it is disabled.

I'm not talking about turning the radio off, I'm talking about turning data connection (GPRS, EDGE, UMTS, HSDPA) off. It's a different thing mate.

also turning off 3g will make the battery last longer since it doesn't constantly look for 3g signal

as the guys here stated, as long as you turn off (or that they're off by default) the data connections and gps,your battery should last a good amount of time.

[Q] *Ridiculously* Bad Battery Life

First day of owning a ChaCha. My phone lost 30% of battery just sitting overnight. What the hell? I went to bed with 75% and woke up with 45% about 7 hours later.
Battery use lists three items: Cell standby, Phone idle, and Display. Shouldn't there be more?
I really want to like this phone, but this is simply unacceptable. Is there something I'm missing here?
Also, has anyone noticed that the phone takes a ridiculous amount of time to charge when connected to a computer?

may be sth wrong with your battery.
mine performs well when standing by

Maybe. I'm also having software issues where after one call, my Dialer app begins draining my battery rapidly, using over 90% of the battery according to the Battery Use page.
Anyway, battery performance on this phone seems so far to be a bit erratic. Eh. I'm interested in trying out a CM port whenever that becomes available on this phone to see if it helps.

Hi, my bettery lasts 2-3 days (on normal usage). Also, the performance improved with more charging cycles...

Do you make calls often? Next time you make a call, could you check your Battery Use page under "Settings -> About phone -> Battery -> Battery use" and see if "Dialer" takes up a large percent.
Thanks!

In fact, could anyone else who has a ChaCha please reply to let me know if they experience Dialer taking up a huge percent of the battery after making a call? You can check under "Settings -> About phone -> Battery -> Battery use".
I know one person on another forum who brought up this issue before I even experienced it myself, so I know I'm not alone, but I don't know whether this is bug is specific to my phone or for all ChaChas.
Thanks!

Hm, okay, thanks.
Yeah, the battery life seems to be quite bad for me as well even when the Dialer issue isn't happening. Oh well.

So since my last post I made a 3 sec call that was it.
Stats show, 10h since charge,
Dialer has used 96% !!! Of battery, that's why the standby is so bad, I'm going to email HTC.
Can the dialer app be changed?
Or is that a root luxury, cyanogen 6 had a decent dialer on my legend....
Sent from my HTC ChaCha A810e using Tapatalk

On my phone, 49% is dialer app, and for me, it's too much, since I do not use phone for too many calls.

exactly the same here ... after 2 mins of phone call - battery stats said that it takes more than 60% of battery use... And the weirdest thing is, that I used internet browser, tweetdeck and greader before for more than 2 hours...

I suggest everyone write in to HTC support so they might get a fix out soon. I've already contacted them.

Another question: how much battery drains overnight while your phone is just on standby? Mine loses about 40% in about 9 hours overnight.

Mine runs like forever, when i just use it for email, sms and a few calls.
I charged mine on Thursday and last evening the battery bar went to orange.

In 7 hours of standby, battery dropped for about 3%.

Mine drains about 15-20% during the night (00:00 - 7:00)

Is your mobile network turned on while you are in standby?
Go to settings - Wireless & Networks - Mobile network.
It's not checked here. I check it only when I want to use mobile operator data package.

Yeah, but why should I have to uncheck that?! I even have push email disabled during non-peak hours.
My iPhone loses like 5% overnight with push and full 3G data still enabled. I'm not expecting iPhone performance, but 40%? What could possibly be happening on the phone that it uses that much battery overnight? I checked my battery use page and my phone is in fact going to sleep when I lock it.
Ah well. I'll try to see if I can isolate this issue to a certain app or something when I have time.

Well, I turned on mobile network, and I lost about 2% within 10 minutes in standby mode, but I will test this a little better tomorrow.

My HTC ChaCha has the dialler issue.
I charge my phone overnight and would expect it to last all day, even with heavy usage. By 1pm (i leave for work at 7.30am) battery life is becoming a serious issue. I then have to charge the phone in order for it to last till i get home at 6pm.
The dialer is always using 95/96% of my battery.
I only make or receive 1 or 2 very short calls during the day.
This isnt such a problem in work as I can charge the phone, but im going away next week and wont be able to charge it every couple of hours.
I was going to buy another battery as i thought this would be a solution but its obviously not the battery, its something to do with the software.

[CM9] Battery drained with no reason

Sup' XDA forum !
So, I recently installed CM9 on my HTC phone (2 weeks ago).
Since 5 days my battery life is very low.
For exemple today my screen was on around 30 minutes (without the battery loader) and the battery is already very low.
Here you have 3 screenshots of the battery utilisation :
http://image.noelshack.com/fichiers/2012/34/1345426160-screenshot-2012-08-20-03-28-11.png

http://image.noelshack.com/fichiers/2012/34/1345425891-screenshot-2012-08-20-03-15-54.png
You can see that the screen seems to be the mainly problem of battery drain, but on the second screen as I said before my screen was turn only 30 minutes a day ! It can't drain 60% of my battery only with the screen on 30 minutes !
By the way the phone is many times in activity ("awake") and I don't know why.
I turned off the Wi-Fi connexion but that does not change anything.
I don't know what "mobile standby" is corresponding to, this is totally abstract...phone idle and Google services too...
I disabled the e-mail synchronisation, but same problem.
Anybody can help me please ?
Sorry if I commited mistakes in my sentences.

Do you have "Restrict background data" enabled?
Also are you using any management applications?
Regardless CM9 with its standard kernel is known to be juice hungry. I'm currently back on CM9, now using the "Stable" release. Still testing battery life. But I can tell you I've underclocked the "off screen" processing, and also using "medium" auto-kill settings in System Tuner, and my phone did not drop a single % over 8 hours of inactivity (sleeping) but quickly dropped 5% when I used the phone in the morning.

There is a data connexion limit with my mobile phone operator (250Mo a month) and I reached the limit some days ago.
I don't know if there is a connexion between my problem and that but if I reached the limit there's no more data.
I have a task killer to check if there's something that should not run but nothing special. I had no problem before I don't know why now there is one.
Anyway I restricted the background data I'll give you a feedback at the end of the day or tomorrow.
(Again, sorry if my sentences are some times confused.)

Regardless of whether you have data with your carrier or not, having background data 'on' will use more battery, as the mobile data service on your phone stays somewhat open.
In saying this though, it doesn't explain why you are getting bad battery life all of a sudden.
Have you recently moved house? To an area of bad reception? A phone that is constantly trying to find signal will drain the battery much faster, then a phone with full signal.
Have you installed any new apps recently? Might be some juice hungry new app running in the background?
Normally if this happens all of a sudden, it's generally for a valid reason.

I disabled background data and I had no problems anymore.
I recieved my monthly 250 Mo data yesterday, re-enabled the background data and everything works fine.
Thanks!

[Q] What to expect from RAZR HD battery life?

Hello all!
First of all, let me just say thanks to the whole xda forum community for making this such a great place to find answers and alternatives to Android users.
So, I bought myself a brand new RAZR HD (XT925) last week. It works just fine, its really fast, but the main reason why I bought it is failing me - battery time. I'm not a heavy user, just have a couple of apps installed like facebook and twitter, eventually I'll listen to some music on it, watch some youtube video. While I'm doing this simple tasks with the screen on, I'm losing 1% of battery every 7/10 minutes. And if I try and load a game just to see, 15 minutes of gameplay will take me as much as 6% of my battery. That is so NOT why I bought this device.
So I went on a journey to find why this was happening. I've tried updating to JB, no better results. Downgraded to 4.0.4 stock firmware, wiped to factory defaults, didn't install ANYTHING apart from what it actuall came with the stock firmware and battery calibration, which I did after changing roms, and the results were the same.
While I was sleeping, the battery seemed to stay a bit better. My GPS and bluetooth are always OFF, I only turn Wi-Fi and 3G on when I need to use it, otherwise its always OFF.
I`ve charged it to 100% 24 hours ago, and BARELY used it, and now its at 34%... is this normal?
Any ideas are welcomed, and if there are other RAZR HD`s users out there with the same problem, please post here! Thanks!

Its not normal especially with radios turned off, and more specifically with 3g turned off. I keep everything on except bluetooth and nfc and can expect a heavy day of screwing around with it, to get 16 to 20 hours with 6+ hours of screen on time. It looks like you really have barely used yours at all.
As for ideas, warranty if you have one? If not then a factory restore might help. Try it from the GUI and if that doesn't work then you can do one by getting into the menu at boot time by holding volume up while turning it on, volume down to select (you have very little time to find your selection, volume up to select , select recovery, then when you get the green droid laying on its back hold both volume buttons down at once and let them go. You might need to do it repeatedly to get it right; just middle click the volume rocker a bunch of times until you get a menu.
Pull everything you want to keep from your internal sd before doing a factory reset because it will be erased.
First things first though, check your wakelocks using better battery stats. Mine are high even when the phone is not in use and with Google Now turned off. Google apps (I think is the problem) still wake it up like crazy yet I get the stated 6+ hours of screen time on a day of heavy usage. Also, I noticed that setting wifi on and leaving it to a policy of never wake up when sleeping is better power savings than having wifi off. It shows up in my usage though as it causes the phone to wake up a lot if wifi is turned off manually opposed to letting the ROM handle it and in some cases it comes on in the background so damn much that its half of the day.
You aren't the first person with this sort of problem btw. There was another thread a while back but I didn't follow it to see if it was widespread.

I have Juice Defender Plus running on my XT925 and I regularly have 75%+ battery left at the end of the day with pretty light use. I leave my GPS on all the time. WiFi is on 100% of the time I'm at home. I leave 4G off 100% of the time as there is no 4G coverage in my area. I find the battery goes down a lot quicker when I enable 4G, even when I'm not in a coverage area.
Try turning 4G off and install JD. See if that helps.

I'm having terrible battery performance after upgrading it to Jelly Bean. I'm running Jelly Bean 4.1.2 update via OTA (98.50.20004.XT925.Vivo.en.BR). I have the screenshots and I can post it here after my phone charges. Battery lasted today for ~10h 44m with HSDPA+ on most of the time. Screen on for about 2 hours with brightness set to 30%. When using it, battery discharges really fast. A simple Temple Run Oz short gameplay takes 5% of the battery. Battery dies in a flick of an eye. I cannot believe it's normal.

With ICS 4.0.4 and green power app installed, my battery would last for almost 3 days with wifi on (at work and at home), HSDPA+ whenever wifi is off and light use for other things. After the upgrade, battery drains way faster and yesterday I had a really bad experience reported.
With same use, my battery lasted 19hr only!!
The solution that I have found so far was turning wifi and 3G off all the time and turn on only 2G. Internet will still work, sync emails, get whatsapp messages, know who is making viber calls. If I need to use better internet speed, like call viber for instance, I will turn my HSDPA+ on or my wifi on.
I know this is not the best solution, because you have to change HSDPA+ to 2G manually all the time (as far as I know, smart actions and the green power app still can't control 2G/3G/4G switch).
If anyone has found a better solution, let me know.

The word is, for some reason, HSDPA+ is killing battery fast.
-Sent from Marino's Razr Maxx-

Today things got worse. Yesterday the overall performance of the phone was terrible after JB update, plus terrible battery performance so I did a factory reset via GUI. When I'm out I need HSDPA+ on because I receive messages thru Whatsapp and Viber mostly and I pay for a better data plan with a faster connection, so I need to use it. First 5% of my battery was drained in the first 40/50 minutes unplugged with a screen usage of about 12 minutes. The phone heated all day long with no usage. I think it's really weird. I don't know if there's an app causing it, or a sync. I have Facebook, Google, Last.fm, Twitter and Whatsapp synced but it was not an issue in ICS. I could let HSDPA+ on all the time with no heating and battery after 6 hours would still have 60%.

That doesn't sound normal at all. Under very light use, the phone should last for a couple days.

What applications are you installing?? This phone has the best battery life of any android phone I've owned.

My Razr HD with ReVolt 4.2.2 ROM and some mods has the best battery life I've ever seen in any Android device.
At this picture that i took last saturday (14/09/2013) i had 3:40H screen time and still got that 65% battery left.

Why do I have terrible battery life?

I just got my Z5 a few days ago, and the battery life is downright AWFUL. With stamina mode on, my phone drains about 1% every minute or two, just while browsing the web. What is going on here?
Here's a screenshot: http://i.imgur.com/uDv2hIs.png

Me too, it's a total letdown. Had 3 hours SOC and around 9-10 hours overall before it conked out on me yesterday

Try airplane mode and see if it improves. This will allow you to use WIFI but halt network search and switching. Check battery stats after a while to see if that helps. Of course, you will get no network dependent communications while in airplane mode so take that into consideration prior to testing. Battery performance will settle down after a few weeks as well but you certainly seem to have a major drain problem and testing will help you locate the cause.

That is truly strange. Any running apps killing it? I just streamed a two hour movie and lost 22%. I read somewhere that the pre-installed AVG was a battery hog. I couldn't tell you because I uninstalled it as soon as I booted for the first time. Are you still running it? That may be the next test.

Have you looked at your Google account settings to see if everything is syncing properly? I have seen this before when someone had an error while trying to sync photos to their Google account, demolished their battery until they went into account settings and unchecked whatever it was that was syncing constantly.
Also make sure you have opted out of Google's location history thing in Google maps where it tells you everywhere you've been on any given day, that can wipe your battery as well. Lastly try turning off the xperia protection that allows you to remotely deactivate the phone, just make sure you don't lose it in the meantime !

I got a Z5 the day it came out and it has done pretty well on battery life, at least until I installed Facebook and Messenger. When I uninstalled the two of them, the battery life returned to pretty good. With Facebook and Messenger the battery was draining extremely quickly. I unlocked the bootloader the day I got the phone and am waiting for TWRP as root will sort a lot of this out.

After 3 Days, i looks like a normale Day use by me around 50% battery. I have allthetime Bluetooth and Wlan on. Whatsapp and Gmail sync. I use my Phone usually for streamming musik over bluetooth around 2h hours, read news and message (Whatsapp) around 2h hours, play some games around 30minutes and some Calls around the same time. My "old" Z1 i had usually to charge ones during the day and of course during the night. So im happy with the battery time @ z5.

Okay, I just turned off automatic Google photos backup, and Google's location history setting was already off. I also turned off my Xperia (the thing that lets me remotely deactivate the phone). Let's see if it works.

Yeah, its still draining fast. In case you're wondering, I keep my screen at half brightness. You can look at the photo I attached.

Update?
Did you ever resolve the issue? I'm getting similar battery life and am not happy about it.

This may be a noob-ish suggestion and one that the phone industry claims isn't necessary anymore, but have you tried "calibrating" the battery by charging it to 100 and completely draining it to the point where the phone won't turn on 2 times and then fully charging it a 3rd time? It may be an old, unnecessary habit, but I've done this every time I get a new battery (or phone) and I usually have really good battery life for the first year - year and a half. The one device I failed to do this on was my Xperia z2 tablet and it suffered for it (i think) although that could just be my prejudice and confirmation bias speaking.

- others suggest NOT to fully drain your phone's battery because you might have troubles turning it on.

Did you by any chance have "Glove Mode" enabled in Settings < Display? It seems that your screen is the culprit. Try disabling "Smart backlight" if you have it enabled and "Tap to wake up".
From the screenshot you posted earlier (History details) we can see that even when the screen is off the wifi is on and the phone isn't actually sleeping. So you got a wakelock on your hands that uses WiFi and doesn't let the phone sleep.
In WiFi settings under advanced (Wifi< Three dots, top right< Advanced) do you have wifi as always on? Change it to "Only when plugged in", also disable "Scanning always available" in the same menu.
Any chance we can get a list of apps you have installed yourself on your phone?
