Several things can cause Battery Drain issues. You will need to isolate some variables in order to get a better understanding of what is wrong. The problem could be a bad battery, excessive current draw from on of the modular components (camera, button, screen) or it could be a problem on the logic board itself.
 
Here are some things to try:
* Always use genuine (and known-good) Apple Lightning cables and charge bricks to eliminate poor quality accessories from the equation.
* Always use genuine (and known-good) Apple Lightning cables and charge bricks to eliminate poor quality accessories from the equation.
* It could be a bad battery.
## Try replacing with a known-good battery or order a good one from [product|IF126-002-4|here].
* You could have excessive current draw from one of the modular components; for example, the backlight, a camera or a sensor. You may notice a hot spot on the phone or screen.
## Fully charge the battery first.
## Disconnect the battery, then disconnect the flexes for the screen assembly, buttons and cameras, leaving only the Lightning Dock connected to the logic board ([guide|23005]). When you are done, re-connect the battery.
## Go back after an hour or more and test the condition of the battery. You will need to download either [http://www.coconut-flavour.com/coconutbattery/|coconutBattery] (Mac) or [http://www.3u.com|3uTools] (Windows) to see the battery condition. If it holds a charge well, add a new modular component and text again.
* It could also be the Lightning port so you could try the same test as above but with the Lightning port disconnected once the battery is charged (connect it back to test the condition of the battery).
* You may have a damaged logic board. Because you already had a chip replaced, it is possible that this IC was either not the problem. There are many components associated with charging issues. Usually it's the Tristar IC but it can be something else. Didn't the repair shop test your device before returning to you?
