Sprint TP2 battery life sucks

Iamdabobo · #1 (**permalink**) 02-19-2010, 02:28 PM

I searched the forums about this, and I can't seem to find a definitive answer. I have installed the 'cleanup' CAB, and will let you know if it works, but it doesn't seem like that will be the problem.

Sprint TP2. Good reception everywhere I go in general.

Running EnergyROM at the moment, but the problem was identical with MightyROM.

When I first turn the phone on, it is fine for a certain variable period of time. Then it will start getting hot like it's doing a lot of work. Even if I do nothing on it except text/call, it eventually starts acting like it's running a ton of background apps, when it is not. When it is cool, battery life acts like it would be about 2 days with minimal usage, which seems to be the norm. When it is hot, I get maybe 6 hours out of it. I tried running a bunch of apps (youtube, opera, WMP, etc) when in 'hot' mode and it seemed to do nothing, so suffice it to say that it is running at max power consumption.

Nothing out of the ordinary is running in the Task Manager. Any ideas on what the heck could be doing this?

Also, this phone has been doing this since a few days after I got it (new). I don't remember if it happened on the stock ROM or not, but I want to say that it did.

Unrelated, but my GPS (google maps and/or weather) is incredibly inaccurate. In general it's about 1-2km off (not even in the big blue circle in google maps). My touch diamond was accurate to within 1m in most cases, what's up with this?

IMO you should return the phone for a replacement. My Sprint TP2 never runs hot. GPS works very well. I use NRGZ's ROM and my battery last all day (7am - 11pm) under moderate use (weather updates, email, stocks, text, etc.).

That's not really an option...long story short got a new phone (Craigslist), bricked it, got it replaced at sprint for free because their computer are slow, so unless i want to pay $120, I'm keeping this phone.

Do this man. I did it and my battery last close to 2 days, and thats with more than normal use.

1. Flash back to the stock ROM. I know, I know, but flash back and stay there.

2. Install the no push internet cab. That way your phone is not downloading unnecessary data.
3. use a registry editor to hack the battery: this can be found in the tp2 hacks sticky.

after that you should be good!

OK so I think I'm getting closer to the problem here. Nothing listed in your post worked, BBHoliday. Here's the story:

I upgraded from Touch Diamond to TP2 a month ago now. My Diamond's battery only lasted about a half a day, but I figured this was because I kept it attached to the computer all the time (texting from an Outlook plugin). So I got the new TP2 and even with the stock ROM, it'd have the same crappy battery issues as listed in the first post. It would seem that after restarting the phone it would be fine for a variable period of time. This latest time it worked perfectly for a week with 2-day battery life, then just yesterday started dying quickly again.

I was about to give up in desperation and assume that I'm just cursed with battery-killing hands, but I had an epiphany last night: I had not plugged it into my computer in the week it worked perfectly. And looking back, I can (roughly) estimate the time my battery started dying quickly to the time that I switched from XP to Win7.

So this thread is now located in the wrong place, but can anyone shed light on this issue? Maybe an Activesync/WMDC bug that causes it to hog memory on the phone after being connected to a computer? In the meantime I'll just connect it only often enough to sync contacts and restart the phone after.

Couldn't be worse than my old TP's battery life. I couldn't even get through the day if I didn't charge it midway or have a second battery on me.

I can run WiFi Router, be plugged in, and have blue tooth on and my phone only gets warm after hours of use.

Your issue doesn't sound like it has anything to do with the phone or WMDC. It sounds like the plugin you run is causing some problems...

I have no battery life issues and I work my device to death. I had to keep 3 batteries on standby for my TP1 just to give a comparison...

The devices generally get hot from a lot of radio use or high CPU usage. The texting plugin you are using or whategver else is more than likely working a radio or the CPU.

Also when a Li-Ion battery gets hot their output drops signifigantly. So a hot battery will go from hours of power to minutes on my laptop (and from days to mere hours on our cells).

Try running Stock, as mentioned, and not running your plugins via WMDC. If those plugins fix the issue yell at the coder to fix the bug.

So you're saying that the plugin (Jeyo Mobile Extender btw) would cause it to do that even when it's not connected to the computer?

Hmm, I did just reinstall it when I reconnected the phone to the computer, at which time it started being weird again, so I'll uninstall it and see how it goes.

There were also some issues with particular versions of custom roms that were built with the Verizon base files, including Mightyrom. If you had Bluetooth on but never connected it to a device it would kill the battery in 5 or 6 hours. The most recent versions of Mighty have fixed that, i don't know about Energy.

BTW, I'm using Mightyrom 2-10 and with moderate use in good reception areas I will still be at %80 charge at the end of the day.

Also, I have no problems with my GPS. It works fine even inside the house and usually shows me in the correct area of the house, well within 20 meter accuracy. Be sure you set quickGPS to update.
