iphone 6s not charge properly
I have problem in charging my iPhone.
When start to charge my phone with 25% (for example), when i checked after 15-20 min is still the same %. Then after i unlock and have a check on it. After this reaction, it normally charge like normal. Is there any problem with the battery?
And i have just used my phone for about 2 weeks then i faced the problem in using whats app, it will hang there (lag) for some times.
