Measuring Battery Life

[andyandroid81891]

Hey Guys,

Just tested my battery (stock) vs my new battery (1750). I got about 4.5 hours running my stock battery down to 25% or so and I'm now at about 6.5 hours running the 1750 down to 27%. When people talk about measuring battery life are they talking about 100%-0% or are they just talking about just 100%-20% or so. This is really the only usable battery range because the radio turns off somewhere under the 20% point. I'm also thinking that my Seidio battery isn't working properly. It was kind of bent out of shape when I got it and felt pretty filmsy. I decided to give it a try but now I'm kind of thinking about returning it in the hopes of getting better life out of a new one.

So two questions here.... what range are you all measuring your battery life through? and any chance that Il' get more life out of a new battery?

100-0 basically, maybe 2-5% and i can get 20-26 hours generally

and the radio doesnt shut off either, not sure why you say it does.

Does this battery push out the back slightly like the HTC 1500mah does?

No, Seidio 1750 fits in perfectly.

6.5 hours and it's at 27?!? Wow you really use your phone a lot. I have the same battery and get well about a full 24 hours with my usage. How long have you been using the battery?

Battery Left is a very nice app; once calibrated it will tell you what your current battery life "is" and how much time you have left. Much more useful that green bars or % numbers, IMHO.

I have ran the phone down to 2-3% and the radio doesn't turn off (are you reading this RIM?)

Once thing to keep in mind (when reading reports) is that is someone is claiming 25+ hrs that will likely include the 8+ hours theat they are asleep and the phone is idle, so in many cases the difference in reports of 15 hrs or 25 hrs may not reflect much of a difference.

I have no desire to leave my phone unplugged at night, so 17-18 hrs is the MOST I will ever get out of any battery.

I've had my phone unplugged at night the last few nights because I've been too lazy to go find the charger when I get into bed. From what I can tell, in the 8 hours that I'm lying there and my phone is not being used I use very very little battery. Maybe 10%.

If your phone can't make it all night unplugged then you've got an app or a setting (GPS maybe?) that is eating up battery.

GPS Does NOT drain the battery! I will continue to beat this into people's heads until the day I die, lol..

Having GPS enabled does not mean that the GPS is locked constantly. All it does is allows applications access to the GPS chip. So the only time the GPS will use power is when an APP is requesting it. If you aren't using a GPS-enabled app like maps or taking geocached pics, etc, your GPS is NOT on, and is NOT draining the battery.

Lets try this then.

Assume I just did a factory reset. What setting could I set on the DInc that would eat up the battery while it was not being used over night?

I really am not a heavy user. Maybe like an hout of Robo Defense mixed throughout the day. Almost an hour of phone calls. Moderate web surfing. Helix launcher 2 running all the time. Facebook and Twitter widgets. Genie weather widget. Battery level widget. Some music. A fair amount of texting using handcent an some email. Screen at the medium brightness but off whenever I'm listening to music or not donig anything. The best I've EVER averaged on this battery is a little over 10%/hour.

Have I got a problem?

Missed my point. If I WANTED to leave it unplugged overnight, I would get 24 hours out of the battery, but since I don't the best I can "report" is 17-18 hrs.

I was just pointing out that folks reporting 36 hours are counting two 8 hours blocks when they are asleep.

And, GPS does not suck juice unless an app is calling on it. If leaving it on is causing battery issues, it is due to some misbehaving app, NOT the setting itself.

Bluetooth, WiFi, bad connection area (where the phone keeps losing signal and has to constantly seek out a signal).

If you do a hard reset and don't install ANYTHING, don't set up ANY accounts (even your google account) on a full charge, you should be able to let that phone just sit there doing nothing for 3-4 DAYS without it's battery dying

As someone who lives on the road, I have stayed at hotels where I would chew through a battery in 4 hrs while I was sitting at the hotel bar.

The Radio is #1 culprit for sporadic battery life. It can often be the difference of a windowed office or a cubicle by the stairs.

It's why (in some cases) some light users only get 8hrs and other power users can go 16.

And there ain't much you can do about it except move or switch carrriers.

I'm heading to VT this week and it will be a good test. VT has always hated my BB's on VZW.

Yeah, having to search for a signal eats through the battery. I just put my phone in airplane mode at work (until a new tower becomes active in June) and turn it on like 5 mins every 1 or 2 hrs to check messages.

Why are people on this site so obsessed with measuring battery life? Is it really that important? When the phone dies, you are out of juice. I'm sure most of you can comprehend that, eh?

Download my "Battery Detective" app from the market (or search for kenyu73). It still needs some work, but it works good for measuring MIN/MAX for signal, temp, drain rate and AwakeTime.

It's still basic right now, but it's good for what it does (for now).. haha..
