poor Battery Life
Lost 35% of battery from listening to music for approximately an hour and half. That's pretty steep, radio was off part of the time, wifi off, bluetooth off, battery saving mode on, blacklight minimum, and screen times out after 10 seconds.
35% is a huge chunk to lose. According to the device analyzer my battery usage is up to 20% an hourLast edited by Shocktribe; 04-12-2012 at 09:04 AM.

What OS version are you using? The newest official release is available near the top of this forum. The various 7.1 versions of the OS all have significantly better battery life then the older 7.0 versions.

only for some Jolt. My Battery life was HORRIBLE with 7.1. I have a picture from meterberry with a 109+% per hour. It would drop like 8 percent about 5 minutes off the charger and with wifi on it would idle at 9 percent per hour whereas with 7.0 I idle at 1.3 or less percent with wifi on.

I am on sprints 7.1.0.267, the only os i've ever had one my phone, I'm a little weary about the leaked os for my 9850, because I don't know how to install it and I don't want to mess up installing it.
Probably sent from my PB via BBBridge on my Torch 9850 - 04-12-2012, 10:12 PM #5 How To: Update to a Leaked/Beta OS

On this page, select the BlackBerry 9850 It doesn't matter that you're on Sprint. I'm on Sprint too and it worked perfectly.
After installing it, Go here to see how to delete the vendor.xml files (I learned there are two that need removal) and they make it easy for you do to it with an exe file; very convenient!
Did I miss anything else? Hope not. It's worth it. Good luck. - 04-23-2012, 02:20 PM #7 What is causing you to use over 7% of your CPU? My drain tests over the last couple of days have given me results of less then 1% CPU. 20%/hour drain indicates that something on your phone is draining your battery, this really doesn't have anything to do with the OS not being up to par.

This to me would clearly mean something went wrong with the installation and the phone is not behaving correctly. I would try re installing the OS fresh after a clean wipe of the phone, then reinstalling apps one at a time. There is no way that the phone should be getting that kind of drain if things were working correctly. - 04-23-2012, 05:51 PM #9
Ya'll must be doing something wrong .. Cause on heavy use I get power from 4am till 8pm :-p

I have BeJoose apparently running, backlight is 10%/20sec., not sure what I'm doing wrong. I set battery saver to kick in at 40% which is now active as I type.
Sent from my BlackBerry 9850 using Tapatalk - 04-23-2012, 07:13 PM #11 I don't think the Battery Saver actually does anything personally. I've turned it on and off and don't notice any difference in the battery life. You already have your screen turned down and back light time out set fairly low. The only thing I've seen battery saver mode do is stop mobile hot spot from functioning. Try wiping your phone clean and re installing the OS, and then re installing apps one at a time. This is the best way to determine if a specific app is causing the battery to drain. Originally Posted by Undenied

I've tried a few and never seen them do anything or seen improvements. Originally Posted by snksvr

I think the best version available, battery consumption and overall performance. With the latest versions have problems with the audio quality when you press the pause/play <- basic issue....

Well, I'm running .402 on my 9860, and after a full day I went to bed last night with my phone sitting at 52% battery remaining. I charge it every night, but I could have probably gotten through yesterday and most of today on a single charge. That has pretty much been the case with all 7.1 releases for me. If getting a new battery would go from getting what you are getting to what I am getting, I'd be getting a new battery.

The culprit that's taking the most CPU is net_rim_bb_qm_peer which by what I can find via Google search, it's BBM. Looking at the Battery Details from the analyser:
(9am - 10am)
Drain 13%/hr;
backlight 4.75%;
Total CPU: 6.3%;
Module w/ higest CPU Time: net_rim_bb_qm_peer 3.46%
(10am - 11am)
Drain 20.99%/hr;
backlight 5.05%;
Total CPU: 7.28%;
Module w/ higest CPU Time: net_rim_bb_qm_peer 2.92%
net_rim_bb_geolocationagent 1.2% (searched a location for only 5 minutes)
(11am - 12pm)
Drain 12%/hr;
backlight 3.98%;
Total CPU: 5.57%;
Module w/ higest CPU Time: Crackberry 1.93%
and I love this one:
(2pm - 3pm) I was writing a long email
Drain 12%/hr;
backlight 6.36%;
Total CPU: 21.3%;
Module w/ higest CPU Time: net_rim_bb_messaging_app 18.72%
When it's idle and just receiving emails and messages, the drain rate is only 4% considered (Normal) There was a recent update to BBM which I now remember I updated it. So anyone know how to downgrade it?

I keep posting the same, sorry about that: Switch 3G off if you are not browsing or downloading. It makes a huge difference in my 9860, seriously, crazy, no matter the coverage or the OS version.
Most instant messaging apps are battery hogs, I do not know about BBM as I do not use it at all.
