    Many of us have had post-Mango battery life issues, especially, it seems, those of us with HTC Arrives.

    My Arrive was rocking a whopping 12 hour battery life on full charge post-Mango (force updated). Same thing with my wife's. And it really WAS 12 hours, not a meter issue. The phone just sucked through power.

    Well, a full reset seems to have straightened things out. I'm now getting 1 day 15 hours listed on full charge.

    Sure, a full reset is a bit of pain from the standpoint of having to set everything back up, but I look at it as a nerdy-nirvana, too: I get to play with my Arrive all day re-downloading apps, arranging Live Tiles, choosing the pictures and music I want on there, etc.

    I still have to do the reset on my wife's Arrive, and will report back to see if this is a universal solution.

    Seemed to work for my Arrive as well.

    I don't know if the Battery Saver function is accurate or not but I went from about 17 hours of life on a full charge to about 30hours of life on a full charge.

    Frankly I don't trust Battery Saver's method of calculating battery life but it's all we got for measuring purposes at the moment.

    I don't trust it either...so I'm going to run the thing back down to zero and see how long that takes, then compare it to the numbers on the battery saver page.

    What I CAN say is that the phone is not draining at 15% an hour, which is what was happening prior to the reset.

    Resetting isn't the most elegant solution, but it does seem to be working. And as I said in the OP, setting the phone back up is kinda fun, a little like getting a new phone all over again. If you see it as just a big ole pain in the butt though, I'm not gonna argue with you.

    In a strange way, you're right.

    After updating my Focus to Mango, I had done "full reset" on my phone (which took more than 10 minutes, I was worried I broke the phone)...

    But even after that, my battery hardly lasts 12 hours. And it takes ages to recharge my battery...

    My Android phone goes from 0% to 100% in less than 3 hours... But my Focus takes 5+ hours to do the same recharge (same battery size)...

    Is my battery bad?

    If the battery wasn't bad before Mango then it's probably not the battery. Maybe give it a few charge cycles to calibrate but there's no way it should take 5 hours.

    A reset on my HTC Arrive took all of one minute so that's strange that it took so long for your Focus.

    only time I have poor battery life on my arrive is when I'm connected to the crappy towers in my hometown that still haven't been fixed in 8 months.

    Yeah, that was me yesterday but a reset completely solved it. Maybe you need another reset for good measure.

    I didn't change any settings but my battery seemed to be a lot better today. However, I didn't use it too much today. Then again, I also don't hit the back button as much to close apps.

    I did a full reset yesterday and I told everyone I was amazed at how much better my battery life was looking. At 95% I had 1 day and 4 hours of charge time left. I didn't get anywhere close to that. I think the full reset is just resetting the battery useage calculator, but battery life will be close to the same.

    The same thing is happening today. I'll leave my phone alone and it'll go down 10% an hour while idling. Is that supposed to be normal?

    There were a couple of small updates after the zune 4.8 updates that were a usb update and a generic windows phone update. One of them appeared to have had an effect on the charging time with usb reducing the charge time. If you did not get those updates you look in the history of srticles here and find them and see if you can still get those they might help!!

    My Optimus is on 18% right now with Battery Saver on. It still says it has 7 hours left and my last charge was 13 hours ago.

    So that's basically a day.

    Today was a good day for me battery wise too. I've been unplugged for 11 hours with 33% left or 4 hours it's saying. That's with light usage and a podcast playing most of the day. I did a reset and hadn't noticed a difference until today. I'm narrowing down the cause of my battery drain. Today I didn't touch the Messaging Hub and I didn't use any apps. There weren't any apps open in multitasking either. I just used Zune, People Hub and IE. So tomorrow I'll do the same thing, except play with texting and see if that's the cause.

    Edit: I haven't used battery saver at all either.
