IPhone :: Standby Battery Test
Jun 29, 2010
I've set up my iP4 as a New phone and did NOT restore from a previous backup. I did a full charge to 100%, reset the data usage and made sure all apps were closed. I put it the phone to sleep (clicked power button) and I went to sleep. I woke up this morning and woke the phone up; 4% was used after 6hrs and 50min of standby time, there was no other usage.
Doing some quick math this would equate to 170.83 hours of standby time assuming a linear relationship; 56.94% of the 300hrs on the spec sheet.
410min/4% = 102.50min/% of standby use
102.5min*100/60 = 170.83 hours
This seems pretty light given the standby time rating. I'm hoping I can get others to perform the same test to get a decent sample of performance, please post your findings.

So recently I have notice that my iphone 4's battery isn't so great. It is jailbroken but I have jailbroken since the first day the hack was released and only a couple of days ago the battery started to drain really fast.I do have winterboard and activator on my iphone.A couple of days ago my iphone would be around 97% or 96% of over night stand by. This is not right at all. Help is fully appreciated.

For last 2 days now my iPhone hasn't been holding its charge, even in standby mode.
I took screen shots of it earlier and at 5:54am whilst in work the battery was at 82% then it stayed in standby in my pocket until the next screenshot I took and the percentage was falling fast, by 9:28 the percent was at 1.
Does anyone here know if there is anything I can do? I have restored the iPhone and also let the battery charge up to 100% from no charge in it and to no avail!
The phone is only a month and a half old and nothing has changed since the last 2 days so hard to understand why it has started doing this, brightness has always been at 100% so that's not affecting it.

I noticed that after I installed the latest IOS 5.1.1 the battery life seems to deteriorated over the course of 1 week use.
The strangest thing happened yesterday. My phone was on %9 battery life and I decided to keep it as I was out and I put it in my pocket. In less than 10 minutes I pulled it out and it was dead, no responce. It actually chewed %9 percent while being on standby. No extras were turned on, bluetooth was off and wifi was off too.
Last night I went to bed and my phone was %53 percent charged and I left it locked next to my bed. I woke up this morning finding my phone completelly dead?
I will monitor it closelly over the next week but I had it for a year and this had never happened. The only common denominator is installing the new IOS.

My wife's 4S has been running down about 50% overnight in standby so I decided to investigate it. The basic problem is that it is showing a usage figure of almost the same as the standby figure while in standby indicating that something is running. After trying all sorts of things (including a restore), in desperation today I restored her backup to my 4S and my backup to her 4S. The problem remains with hers which is really strange indicating a hardware problem, but the fact it is showing too much usage would indicate software.

I was just wondering what everyone else's experience with the battery life was. What's your best standby and usage time and was it with push email on or off?

I have a red 920.So I charged my battery to 100% and took it off the charger. This was in the middle of the night (yes, I'm a night owl). But I did it because I wanted to test it with absolutely no use. So I set the wifi to always on and left the phone. four hours later I checked the battery. It was down to 60%. This was after absolutely no use. The only thing I have is two email accounts set to fetch every hour.
i then recharged to 100% again, changed the wifi settings back to the original setting and left it for another 4 hours. The battery was down to 63%. Not that much different from setting wifi to always on.However, previously my phone would lose at most 1% after idle for even 8 hours. As I stated my battery life has always been very good.the only difference was the OS update, no new apps, no setting changes, etc. I have to assume it was the update. I know it's not really scientific and partially anecdotal but it is what it is.

I have to charge my Satio twice a day. Even though I did not use it to talk, just idle to test the battery, it only last for 20 hours. I am really disappointed with this situation. After refer to the Satio website it is stated the talking is 4.5hours. Do i need to send it to the service center for warranty claim?

My curve's (which is 2 months old) battery is dying after only 18 hours on standby, and it takes it forever to load anything. She just gets stuck with the little "loading" clock in the middle of the screen. That, plus the fact that I fear answering a single call will make my battery die at the rate its going. Is there anything I can do?

Last night I put my galaxy 6s into battery save mode, charged it to 99% and put it on the nightstand. This morning (8 hours later) my phone is at 48% charge. Do I have a bad battery or is there a setting or application on that is draining the battery? Battery shows 46% battery usage by cell phone.
