There are a lot of negative feedback with this phone but I haven't got them here. It does not mean my Mi 4i has no issues. It had had one with the display being flickering very occasionally. It was a month ago when xiomi claims they fixed for me after returning it to their center, However it again happened to mine a few days ago but it was when my phone was somewhat hot.
So I learnt that it is important to keep the battery in good health and to avoid overheat problem. I find the screen function "battery usage" a very helpful tool to verify no application is draining too much my battery (thus causing heat problem).
Right now my system shows 14% for Android sys, 7% for Android, Whatsapp 6%, Handwritten input 4%, voip 2%, mail only 2%, gmail 1%. My battery is now down to 17% full after it was fully charged 24 hours ago, with normal usage since. The system now reports I still have 13 hours of phone life (if battery usage is unchanged).
There are about 6 email mailboxes to check for my phone so it is very important not to allow automatic email synchronization. It was found that email sychro actually eats up considerable battery power and I suspect that was one of the major issues I had initially.
It was 3 months time after using this new phone. Normally I do not have to recharge the battery more often than daily. In case my use is normal (no gaming, no google maps, only phone calls, some web browsing, instant messaging) I trust it continues to behave the same. I do not know if battery performance could be better with phones of other brands but at least mine is now comparable to what my another friend told me with his phone of the same make/model.
Baban, 11 Jun 2016I need help from anyone who can ..my mi4i phone faces a problem. While dailing any number the ... moreBaban: Strange that I saw a lot of negative feedback with this phone here for which the experience I and my friend do not encounter.
Initially I was annoyed by having blank screen also. I refer to the case I must press the power button on the side to restore the screen. Lately I discovered in my case it is the wrong setting with "battery profile". You have to go to settings > Ad' settings > Battery >
By default the system choose a build-in profile called "default". I think xiomi has set up the default which turns off the screen (put to sleep) after 30 seconds which is too short. The user is not allowed to change its value. All we need to do is to create his/her own profile with a 5 minutes sleep delay and select it as the new battery profile.
This is my two cents.
