Ok, so when I had a Lumia,900 on WP 7.5 the battery was AMAZING! But now that I have a 920 and I have a lot more games and stuff to play my BATTERY SUCKS! If you have battery problems like me, do you want to help me attack microsofts with demands to fix battery issues in the OS? Please and thank you :) lol

Could you show your usage pattern? If you play a lot of games, you'll end up killing the battery (since the CPU + GPU combo is more power-hungry) and take note that the screen is an 4.5" IPS LCD Puremotion HD+ screen meaning that it drains the battery faster than the AMOLED screen on the 900.

Also, how long does the battery life last?

I do not play ANY games, because that absolutely kills my battery, and I just check up on my email, browse the web a little, and do some social networking all with battery saver on, and it will die in about 6 hours, without battery saver it would die in 3 hours, and Microsoft already said this was an OS problem

Do people not check their background tasks, and disable stuff they don't use?

I have the bare minimum enabled, and easily get 2 days to a charge, used to be 3 days before i turned on the keep wifi enabled when screen off.

I keep it on battery saver all day! And I have only 2 background tasks on! And a smartphone shouldn't have to make me turn off background tasks especially windows phone with the live tiles and lock screen!

Its not an OS problem, I routinely get over 24 hrs with moderate use on my Ativ S. If I start playing games it sucks but that is to be expected.

[svenhassel]

Maybe you have a defective unit, it should´t work like that with such light use, and the settings you are using :(

How new is your phone? I found the first few weeks my battery was HORRIBLE too...but as the days pass, it seems to be getting better over time with each charge,.

my phone is about three months old and I replaced it before and it still had sucky battery

Oh crap ok...yours is older than mine so my point doesn't stand. Nevermind.

I don't think this is an OS issue. The 920 has a stunning screen. Unfortunately stunning screens often have stunning power requirements. Even with battery saver on, having the screen lit up for long periods will drain considerable power. Also, games are often CPU/GPU intensive. These processors draw more power when under load. So if you're playing lots of games for hours at a time, your battery will drain fast. It's the trade off for having powerful hardware and gorgeous screens.

NOOOOOOOOOOOO!!! I'm so sad now that there is no solution for this because I want to have my brightness on full blast to show off to everyone the awesomeness that is Nokia and windows phone! But why does the iPhone5 not drain battery as much even on high brightness (I keep mine on low) and I'm pretty sure I read somewhere its an OS problem here let me check

My battery last for more than a day on most days, despite me having wifi on 24/7 and location services. My biggest problem is video calls with Skype. After about one hour it has gone from 100% to almost 0%. Funny thing is, even tho i plug the charger in and the charger is connected to the wall-socket my 920 still dies during a Skype video call. That is an insane amount of power needed according to me.

I have read tons of forum posts about the 920´s battery problems and something seems off for sure.

If you don't play any games then you should uninstall them as they are taking up memory. If you are using the light them you should switch to the dark them it will save battery life. There are many tips for increasing the battery life. MS has some on the www.windowsphone.com site and there are some in the 920 forum sticky's

My battery sucks big peepee too....and I replaced my device twice. Have barely any background stuff running besides weather.

[Jakoh]

y'all need the Lumia 720. Great battery life. 24hours typically.

[neo158]

This is most definitely not an OS issue, battery saver on my ATIV S shows 1 day since last charge with an estimated 1 hour remaining with 14% remaining battery life.

[falconrap]

My 822 has generally had good to great battery life, but the last day or so, it started running the battery at a consistent 10%+ per hour. I was stumped and started killing off background processes, checking my signal, and doing other minor tips to no avail. Then I realized that I had gotten Chronos Calendar up and running the other day. Since I also use Simple Calendar, and like it, I decided to uninstall Chronos and the rate dropped below 6% (currently at 3% with a news app running). My best advice is to suspect one of two things causing large battery drains: 1) an app that is not efficient when installed and running background tasks and/or 2) poor signal strength causing constant tower hand shaking. If you have excellent signal strength, then start removing your apps until you find the culprit.

that's not true, that's just the battery saver being dumb that's happened to me in fact it said "estimated time remaining: 2 days 13 hours" in reality it gave me about 5

Do you know how to downgrade the signal yo 3G? I'm on at&t

This isn't an OS problem though. Notice it says "Estimated time remaining", this does depend on what you're using on the phone but again it's just an estimate. But without you seeing my phone you won't believe me that a single charge lasts me all day.

If the option is available on your phone it's in Settings>Cellular. You can set the max speed to 3G if the option is there. I've heard some AT&T 920's have it and some don't. My VZW 822 does not. Have you removed all of the apps you installed to see if the battery drain goes away? You can also use the speedtest.net app to check you signal strength for data. You should be getting well over 20MB/s with LTE/4G with low latency.

nope I don't have it and actually I found a trick at the official windows blogs saying that you should let the battery go down to about 20% and then charge it up to 100% but don't leave it charging after 100% and do this for 1-2 weeks and then the battery will be stabalized and improve so I'm gonna try that first and if it doesn't work then I'll uninstall apps :(

This is completely unnecessary and pointless with Lithium-Ion and Lithium-Polymer batteries. These batteries don't suffer from the 'memory' effects that many earlier types of battery did. So 'conditioning' does absolutely nothing for the newer batter technologies found in modern smart phones. The perceived 'conditioning' effect is usually attributable to people playing and looking at their phones in the first few days/weeks of getting them. After a while their usage pattern drops back to normal and the battery lasts longer because the owner is no longer prodding the screen to life every two minutes to admire it or show it off to friends.

Another factor is that when you first set up a new phone there is often syncing and update stuff going on in the background for a little while when the phone is awake. This can make the battery appear to drain faster during the first couple of charge periods.

It has been reported that the battery monitoring function on some phones need a couple of recharge cycles to get 'calibrated'. This might affect the predictions of remaining battery life (making them more accurate over time), but shouldn't affect the battery life you actually get (from full charge to phone auto-shutdown).

Also you can't overcharge the battery in any of the current generation Lumia phones (or any other fairly modern phone that I know of). The charging circuitry does not 'trickle' charge the batteries once they are fully charged. It actually disconnects the charging current completely. So you simply can't overcharge them regardless of how long you leave them connected to the charger.

So bottom line is, batteries in modern smart phones don't need any special conditioning or care with charging. If you're battery is draining faster than it should it's either a software issue (poorly designed/rogue/corrupted/crashed app or OS process) or a hardware one (dud/failing battery, faulty phone circuitry). There are lots of things you can do to prolong the battery life of your phone. Conditioning the battery is not one of them.
