How to Add a Aditional Battery to a Smartphone (for Using It Days)

Its something i doing on all my portable devices.. today hav get a old smartphone .. so did it again.. this time spend a little bit time in documentation.. its realy easy, and if changes the rear cover and the origial accu cell the smartphone is original again.. ) no big discription, have write the text into the pictures.. just watch..

Until now all modified devices running fine.. only thing i need to do is chleaning the soldet accu contacts sometimes..

please watch pictures in original quality.. and not only the preview..

The Required Tools and the Circuit..

als discribet in pictures..

maybe a ebay link for the second glue (cheapest i find.. buyed 11pcs.. 20g 1euro.. )

its a simple soltering work.. but the protectionboard is importend.. (alsways protect against high current, compleet discharge, overheating and overcharging.. also they expand tzhe accu livetime)

you can also use a other Smartphone accu, or phone accu.. but only connect + and - ..)

The Mechanics

The optical foil is from A broken LCD tv backlight.. i have used perspex before but its getting crannies after a while..

The Art

CATS are Awesome!

Connecting the Li-ion Case With Smartphone Case

Be carefull if use secondglue.. its a strong glue, but on wrong places its realy bad..

Done.. Some Other Modified Devices:

For the Lenovo A806 mod have stend most time.. searching Li-po Batteries exactly maches to on the case.. have used 2 from this: http://www.ebay.de/itm/331803522405 they alrealy have a prodectionboard.. )

the smartphone itself don't know that there is a modifikation.. the acco just discharges much slower.. no chrargingdevice needet, die adidional accu charging with the original batterie at the same time.. but it needs a little more time until the batterie is full charged.. after adding the accu, dichcharge the phone below 15% and run accu calibration.. and don't remove from charger until 100% (its usefull to have the correct time howlong the accupower reaches)

Final Destination and Another Short Mod

The modificated Smartphone Accu testing is done.. Worktime 8 days without charging.

have configured it for a simple foobar WLAN remote , display turn of after 30min..

also have modified another smartphone for someone (short 10min work with old handy Li-ion accus).. its not looking so nice, but its mechanic stable and running awesome.. =^.^=
