IPhone :: Draining Battery By Leaving Wifi Enabled
Jul 29, 2010
Our wireless at work has a mac table setup with unique keys so anytime someone forgets/otherwise screws up their wifi connection they come to have it reset... Everytime I make a comment about how they are really only draining their battery by leaving wifi enabled 24/7 yet they continue to do it..
SO - what do you use WiFi for?
I know there are some (very, very few) apps that require a wifi connection..
Facetime requires WiFi but at this point it's more of a novelty than anything else..
Throughput is a little better but not enough to justify the additional battery drain..
The hotspot app (as soon as the IP4 jailbreak is released..)
Checking mail/browsing the net in an area with no at&t service..
That is all that comes to mind.. I think they just like to enable it because they can, but let me know if I'm missing anything?

Lately I've been leaving 3G on and the battery seems to drain rapidly fast, even when I have it locked it drains quiet a lot and sometimes it also lags. I have a iPhone 3GS and I was thinking whether erasing and restoring it back to normal would work maybe.

iPhone 3GS

I leave my WiFi constantly turned on on my phone. I use WiFi at home and work so it will automatically connect when I'm in those 2 places, but anywhere else it isn't connected. Is it still using battery even if its not connected? Does it search for a connection when its not connected, sort of like the radios searching for a cellular signal?

I have recently upgraded my iPhone4S from iOS 5.0.1 to iOS 5.1. Since then I observerd my battery is draining rapidly when internet connection is active either WiFi/3G. Even the phone is kept idle without using anything, under settings->usage its showing as used (Usage Time & standby time both are increasing) When internet connection (WiFi/3G) is kept off, battery backup is good and settings->usage is showing only the actual iPhone usage only. But with internet battery drains very rapidly almost 20% for an hour or so.

So the last few days I've had problems with WiFi disconnecting and reconnecting over and over and thought that was the cause of my battery draining tons faster then normal, used to last at least most if not all day with pretty constant use and now it's barely making it 5 hours without needing a charge. Att pushed the 4.4.4 update today and after turning the WiFi smart switch back off the WiFi problem seems to be better but my battery is still draining, just not quite as fast.

Ok seriously... this is BS [exscuse my language] but this is my second Blackberry Curve 8900 and second battery and I've only had blackberry for 11 months. The first 8900 the battery started draining rapidly after 4-5 months and kept deleting everything on my microSD card. I had it replaced... now this second 8900 is doing the same thing. I've had the second 8900 for 4 months. I charged it all night, took it off the charger at 7am; by the time i was out of class it was red and going dead at 10am!
I do not have wifi on, no bluetooth... and also, it pings [like I've gotten a new text or email], the LED light will flash red but there won't be a message or missed call!
Anyone have this issue too? I am having it replace for the second time, this will be my 3rd blackberry 8900. If I have issues and problems again, I will have to say goodbye to blackberry. Even though I love everything about BB, the style, the keypad and so forth, I need something that won't die on me after 4-5 months!

I bought my device 2 days ago, and based from my observation, my battery life doesnt last that long.. I was an iOS user before I switched to Sony.. I can tell the difference of battery life.. wherein Sony should have more battery life than iOS phones.

Since updating my E71 to v500, and then to v510 just recently, I have been suffering from terrible battery life when the phone is connected to a WiFi access point. I'm sure it's not a hardware problem, as I noticed it as soon as I first updated to v500. If I leave the E71 connected to WiFi, my battery will be flat in just a couple of hours and the phone is noticeably hot to the touch. I initially thought it may be the battery being a problem, so I bought a new one but still exactly the same.
On another point, the Podcasting application is now terribly slow. I wish I would have never updated from V300, which was fine. I've tried reinstalling the F/W a few times, and not restoring from a backup, but still the same problem. I also read in another thread that someone deleted the Lotus Notes application, and it fixed this problem, but alas, has not done so for me.

I have SmartActions set up to trigger when my location is home to turn on WiFi and turn off data. Similarly, I have a trigger when I connect to my Bluetooth in the car to turn off WiFi and turn on data.
The problem is when I am leaving the house but not going to the car. Is there a way I can determine that I am leaving my house or disconnected from my home Wifi so that I can turn WiFi off and data on?

I've been without BIS for over 3 hours now since i've left my house this morning. It happens everyday and is getting worse Sometimes I lose it for 5 minutes, but 3 hours is ridiculous! I'm still connected to 3G. I can talk on the phone and I can use the browser for internet. But i can't get my work emails and my apps don't work. I tried resending my service books nothing I turned on and off all my services on the phone nothing. I run the connection diagnostics and it says Blackberry Registration: No. I updated to the latest leak .161 and that didn't help.I found a thread on Crack Berry where numerous others are encountering the same issue, so I don't think exchanging the device is going to help. Someone from Blackberry please fix this! This is a serious issue!

So, I am having battery draining issues with the iPhone 4S just like I had with my iPad 2 (I am guessing that it has something to do with my operating system in both cases). I restored my iPad 2 and it is working fine, but since I bought my iPhone 4S through Verizon, if I restored it back to original settings, would I have to take it back to Verizon to do that?Or is there a better solution to the problem?

My battrery has been running low quickly . For instance, I charged it yesterday and when it was done charging I made a phone call. I was on the phone for about 11/2 minutes. After I got off I looked at my battery and it was down 1/2 a brick. I've tried removing the battery for awhile, but it doesn't seem to help. I talk on it a lot through the day so I can understand it needing charged at night, but 1 minute off the charger and it's already losing power? I don't use the internet that much, but I do play games. The phone is about a month old. Any advice?

I took my iPhone4 into the Apple store so they can look at the battery issue I think I am having. Here is a screen shot of the performance of the battery before my visit.
They said the phone needed to be reset to a new phone because I initially choose to use the backup of my last iPhone when I initialized and there is probably a software problem which is draining your battery faster.
Me: Well, Ok. But can you please run a diagnostic on the phone before we reinitialize.
Apple: No. There is noting wrong with the batter, this is a software problem.
Me: Ok.
So this next screen shot is after using the phone after initializing as a factory reset.
I am not seeing any difference in the performance if anything it is a little worse.
Do you all think I have a problem or is this normal performance for the iPhone4 battery? Apples website claims the phone should be standby 300hours, internet, 10hours.
I haven't been doing any heavy use just normal internet use, some angry bird action and a couple video shots.
What type of performance are you all having?

I recently upgraded to 5.1 on my AT&T 32GB iPhone 4S. I have noticed that my usage time since last charge, taken at 1% battery level from a full charge, is about 4 hours and 45 minutes of usage and about 9 hours and 15 minutes of standby time. Is anyone getting battery drain this quickly? I have followed all the battery saving tips from restricting Ping and iAds to getting rid of most notifications and removing a lot of location services except for Maps and Safari. I also adjusted brightness to auto and deselected the "Send usage logs to Apple."

Charged my iPhone 4 16GB Black unit at 7.50 a.m. The battery shows full 100% at 12.30 p.m. 30 minutes of music, 1 minute of safari browsing, & received couple of phone calls. After use my iPhone 4 for only this usage and just few hours of standby, at 7.00 p.m. on the same day my battery shows 45%. VERY WORST BATTERY AFTER UPGRADE TO iOS 5.1. Does anybody else who is iPhone 4 users face the same problem in their iPhone 4?
