The Galaxy J5 has the same battery capacity as a one time Samsung flagship smartphone, the Galaxy S4. More than two years later, the Galaxy S6 has an even smaller battery albeit with some enhancements to get the most out of it. The Galaxy J5’s 2600 mAh battery provides more than enough power to last you through a typical working day when texting, calling, light browsing and social media activity is the norm.
There is no specific time you can expect it to take as this varies with usage. 4G/LTE just started rolling out last year and not all parts of Nairobi are covered yet. If you happen to live or work (or both) in an area with excellent LTE coverage and happen to be online most of the time or all the time on your phone, the results are likely to be on the lower side. Typical battery consumption over 3G should be balanced regardless of usage. Battery life is fantastic when you’re dominantly on Wi-Fi. I managed to regularly get 6 hours screen on time when using the device exclusively on Wi-Fi and for about an hour and a half on 3G data whilst cheering on Manchester United to its first UEFA Champions League appearance in two years.
Even when you are about to run out of juice in the middle of the day, you can still have the Galaxy J5 spare some for the road by turning Ultra Power Saving Mode, a feature that it has that is meant to shut down all but essential apps and features on the device before you are able to plug it in.
