    I've heard that 8.1 has a battery issue problem. As I bought my phone, I updated it to 8.1 and haven't experience the performance of 8.0.

    Im more concern on its battery life. It only lasts 7-8 hours on watching movies. And when Im surfing the net over wifi, it only lasts 14 hours straight.

    I want to downgrade my software to 8.0 to experience good battery life as they recommend to turn back to 8.0 as it offers good battery performance. Im just worried that it might affect the warranty.

    TIA for the answers :)

    Which phone is it? And are you on 8.1 with cyan, or just the developer preview? Because with the cyan firmware, windows 8.1 and windows 8.0 on phones are pretty much identical for battery life, as far as I know. But, if you're on developer preview, that's been known to kill batteries just because the operating system is optimized for it.

    As I checked. Yes it is Cyan. What will be your recommendation then, if they have the same battery performance on 8.0?

    Oh and btw, whenever I charge I oftenly uses also my phone til it reach 100% but I always over charge it atleast 45 mins for a good performance. Seldom I fully charged, but mostly i charge it only at 80% give me some tips on how will I last long my batter lumia 1320. I've tried optimizing my settings, just a bit of battery performance. By the way if fully used the phone with wifi how long does it usually last?

    Not familiar with the 1320 directly. I'd look up Microsoft Mobiles website on it, that will tell you the ideal battery time.

    How to improve my battery life please? Will I still continue to downgrade my software to 8.0 for a better performance?

    Do you use what's app? I have noticed that many on this forum that have battery life issues use that app. Also Use the battery sense app to stop apps from working in the background that you don't want or need. Also when apps update some of them turn themselves back on for working in the background. Adjust your glance screen for interval instead of constant. And when you know you wont be using WiFi turn it off so it isn't constantly searching in the background. Hope this helps. Oh yeah if you don't use nfc turn it off.

    I have done it all same problems occur. Upon surfing the net through wifi it only lasts 8 straight hours, I guess it's a disappointment for a 3400 mAh battery?

    If that 8hrs is "on screen" time, that's really good.

    Battery tips:
    -Always charge to 100%
    -Try to deplete battery as much as possible before charging everytime.
    - Try to avoid constantly charging when you still have plenty of juice.

    Batteries perform better and last longer because of this.

    Having wifi, NFC, etc seems not to affect battery life, but things like Glance screen and or using a background pic on glance screen does however.

    Almost "Amen, brother." Glance uses nothing, effectively. Check it out under the Battery Saver app.

    OP is all over the ballpark, little makes sense.

    6-8 hours of web browsing straight no turn off, i was browsing facebook, youtube and watching animes the whole time. Does it sounds good performance for a 3400 mAh battery? Still not satisfied on answers huhu.

    My classmate says, always charge your phone whenever it hits 20% and charge it only at 80% do this in 29 days and on the 30th, drain your battery to 0, and dont use it for 5 hours then charge it till it reach 100% as this calibrates the battery. Was now confused. :3

    Remember this is a lithium battery. Lithium batteries do not have the "memory effect. Ideally with lithium when it gets down to about 30% its time to charge. The number one killer of lithium batteries (and does so quick!) is draining ot dead or near dead. And leaving it that way for any length of time. Doing that will destroy a lithium in no time. No offense but the draining it down does not apply to lithium and if anything will hurt it. With older battery types that's good advice, but not with lithium.

    How will you even downgrade to 8.0? As far as I know Nokia software recovery tool doesn't let you to downgrade to 8.0 anymore! It directly installs 8.1 with cyan.
