Charging issue on Z4 tablet

[Ilirg]

Hi

Wondering if anywone else have the same issue as me. I really love this tablet but the charging time is terrible. 10% per hour with the tablet switched off. This is bugging me so much. I tried with my charger from samsung wich has a bit stronger output but same thing there. If i use The tablet while charging it will still not keep up even if I decrease brightness to 50%. Is this normal? I switched from ipad 2 air to z4

Allright guys Im finally starting to realize that what I read at other forums is starting to actually be true. Today I got from 74% till 100 in 45minutes. With the stock charger. And the tablet on. I guess its true that it takes 4-5 days for the battery to start working properly. I will let it discharge to zero then time it if I can to see the difference. To be cotinued....

I don't think there should be any problem. From experience using a similar charger with my old Z tablet, you should use the 2.1A socket, and the tablet will take a LOT of the charge - you will probaly get a maximum of two charges from the external battery, if that.

First Sorry for my Bad English.

For me here ist a Bug,

When Play a Game XCom: Enemy Within and plug the Standard Sony Charger the Accu decrased slowly.

The Sony Charger have not enough Power?

 The Sony Contact Formular not work. Send Button not clickable?

My Z4 shows erratic charging behavior,  battery shows sign of charging but the orange light goes off and change stops at 50 or 60%. Restart sometimes turns charging on for a short time but percentage is not growing.  Battery app shows strange jumps in Voltage and temperature. 

I have used different cables and chargers but it does not help. After about 3 weeks the battery should be formed,  although I have not discharged it completely,  just tried to charge it overnight,  from 30-40%.

Very annoying.

I have other charging issue. After latest android update tablet can be charged from wall only. Any attempt from PC or power bank is rejected.

Do you have similar experience ?

My Z4 Tablet charges very slowly despite having a new charger and cable and being checked by a computer technician.

It also loses charge even when charger cable connected
