Bro, this issue started as you got the phone or it was working fine and only recently develop issues?

And if you don't mind me asking, which telco did you get yours from?

I don't see why not.

To be sure, try out the fingerprint recognition after you have multiple registers. Then try out other fingers which is not in the system. If it works then good.

My advice it that, when ever you want to use the phone, try to wipe your thumb (if thats the finger that you have registered ) to your shirt/pant before touching the sensor. At least on contact there won't be sweat on the print. Also its also handy to have one of those microfibre cloths readily available on your person. I for one carry one for my glasses. And now and again i woud clean my glasses and right after the hp too. It keeps the dust and grime away.

Do you mind sharing which SP you are using?

My SP have the cutout at the round sensor part. and another cutout for the sensor at the top too.

Bro. Try this. Exit the app, then press power button until the slider appears, let go power button. Then press the home button and keep pressing until the slider disappear, black screen and then the home screen reappear.

Then open back FB and play video and see ok or not.

Bro, my case totally opposite. This is what I observed when I first got the ip7. I ve never used the charger that comes with the unit. What I used since my ip5S days is a Ipad 10w charger + anker powerline cables. When first start charging, the phone does get hot significantly till about 80%.. then the het will dissipate till 100%. All in around 2 hours can get full charge from 20% lebih kurang. I also notice that when it reaches 100%, a popup will come out stating that it has full charge 100%. For a few days I monitor the heat even I leave the charger on after full capacity, both my charger and phone does not have any heat too.

I have also checked and confirm that when hooked up to charger and charging, I can use the phone like normal even answer calls without any ill effects.Also no issues with thumb print recognition and all apps working fine.

BTW my unit, ip7 came from Maxis. and updated to ios10.2.1. I have a Spigen Glazz SP and Neo Hybrid case.

Yup. These smartphone will have circuitry that stops the charging when it has reached full capacity. Leaving it overnight wouldn't harm the battery. What would shorten the life of the battery ie the Lithium Polymer is constant <20% charging to full. If it was Li-Ions type, then its better to charge it <20% capacity. Li-Po, prefers around 50% capacity then charge to minimise excess heat.

Yup me too. I couldn't use it with my macbookpro.

Wireless headphones are still bloody expensive. If you are concern with sound quality, it can get very costly.

No. What I am saying is to make it a habit to charge the iphone around 50% capacity or more. This will minimise the duration in which the phone is subjected to heat due to charging. What we are trying to avoid is unnecessary heat due to charging. If charge from 0% capacity, obviously it is on fast charge all the way till 80% then it throttle down until finally trickle charging for the last few percentage. The battery will then experience high heat for longer duration compared to if charged at say 50% capacity to full. I have been using this habit with my ip4, ip5S, ip6 and ip6+ and so far I have yet to replace any of their original battery. So basically, I have chargers at home, in the bag, at office and in the car too. I charge my set whenever possible. Its becoming secong nature somewhat.

That scenario you mention applies if the battery is of type Lithium Ions (Li-On), smartphone are having the Lithium polymer (Li-Po) cells. Anyway its some habits that would take care of the investment.

Watching video and graphics heavy games do tend to work hard both the processors and graphic chips, and then if it is online game, even worse as all the system is all working hard simultaneously. Having a case and depending on the type of case also make a notable difference. Having IP67 weather proofing is also welcome addition to the ip7/7+.

I used to use Battery Doctor but have since just rely on the built in app. I stopped using the 3rd party apps after an article from Macworld came out in August 2016. To summarise, these apps are not useful and are just there to promote adverts, shareware etc etc. You can monitor the battery from within ios itself.
