actually i do heavy browsing...so 6hsot already impressive...im a heavy user so Im dun think i will get 7h sot

I also play some games...anyway if i switch on power saving mode and use lightly I dare say even 10hsot is possible on single charge but not proven...maybe I'll try someday watching streaming vid does not really drain batt

Thanks to Benny for the recommendation of cm browser. So far I'm loving it! My antutu result is only 44451.  What are your guys reading?

Not sure how Antutu scoring works, I noticed my Antutu score getting higher and higher from 6 months ago to now, with the same phone (Mi3). Every time Antutu is updated, the score changes, usually higher.

Where got such thing one. My Note 4 hot or cold also like Bugatti Veyron. Never drop till Kancil performance before.

I think you stay beside volcano!

So you need to use this phone in air con room 

after u disable all thoae unused crap it will be much faster then note3

Do u have a memory card inside your phone ? If u do , take it out , restart your hp and monitor it for another 1-2 hours . IF the temperature still the same , copy out what's important in your internal and format the internal sd . Dont copy back in your files immediately . Leave it for another 1-2 hours ....

Chances are u have a media scan wakelock . Some corrupted files especially photos/videos from messaging app like wechat , whatsapp , etc tend to cause it and the phone is working non stop to scan it over and over again . I cant be sure , the only way to be sure is to install wakelock detector and i dont know any that dont require root . So , trouble shoot it manually for now

Mine does that for about 30 mins or so, then it drops down to normal again.

I think it has something to do with what's on our sdcards, as it is the same with 2 sdcards I put in.

The .nomedia trick helps, because before I did the .nomedia file, the phone was on for about 2 hours or more while in my bag. I only noticed it when I took it out.

Take out your sdcard and run it for a day.

Or perhaps you can remove all PDFs, pptx, docx and xlsx from your card first.

If you have no card and it is doing this, please see if the IndexService is running.

If no IndexService is running, you could have some fault in the unit.

Mine is caused by IndexService, and I'm fine with it killing some battery since I still get 1 workday's use out of it.

If all suggest here you don't have. High possible your unit got problem. Better check with Samsung SC as soon as possible for a replacement.

Your media server is high .... Check your gallery to see if u have corrupted photos . Sometimes , songs/mp3/audio files also can have this problem .

Usually when hot, the CPU will throttle down speed. Hence why it become slow.

Thanks god I didn't face it.

Last time I do face it in dunno which phone. Long ago. I let it complete the indexing. I think it took a week or less than. After that I never face such issue. Touch wood.
