My Samsung Galaxy Note screen starts to flicker whenever it reach 50% or less and then the battery die off. The following is the scenario when it start to happen

Samsung Galaxy Note Screen Flickering

• The screen starts to flicker
• Shortly later, the network is lost
• The phone shuts down

You can restart the phone and u get 1% to 5% of battery. After this you have to start charging, you will see it go to 40% pretty fast and then charge normally

Root Cause
You will see the battery is bulge or swelling in the middle. If u put the battery on a table and u can spin it very fast, then u know the middle has swell up. The battery is no longer flat.

Replacement
You need to purchase a replacement battery to resolve your problem. Samsung only carries a 6 month warranty on the battery.
