New FCC filings have listed a phone with 3600 mAh battery that is likely to be the Samsung Galaxy S7 Edge. This is an upgrade on a battery size, as the last year's Edge only had a 2600 mAh battery.

The Samsung Galaxy S7 should have a smaller battery, and word on the street is that it will be 3000 mAh. The FCC filing confirms that Galaxy S7 and Galaxy S7 Edge are shipping to major US carriers too. As we said a few times before Qualcomm Snapdragon 820 will occupy some versions, mostly USA while the Exynos 8890 will ship in Asian and some European phones. Qualcomm still has a modem advantage over Samsung own SoCs.

It is expected that the Galaxy S7 Edge will have a 5.5 inch screen as this size is slowly becoming a standard for many phone manufacturers. One of the most prominent phones with larger screen, 5.7 inch to be precise is Google's Nexus 6P which has a 3450 mAh battery. The mathematic behind a bigger batteries is simple, the larger the display, the bigger the battery required. No surprise there and Samsung has realised that battery life has been a major concern for end users.

People want to heavily use their phone from 7 AM until midnight or a bit later before they get to bed and leave it on a charger. Is that too much to ask Samsung?
