Alcatel Idol 4S Review - Battery Life and Verdict Review


Alcatel Idol 4S – Battery Life

The Idol 4S is powered by a non-removable Li-Ion 3,000mAh battery. With regular use I managed to get between one and a half to two days’ use out of the phone.

Regular use entailed using the Idol 4S as my main phone, taking and making a few calls, listening to music during my commute, sporadically checking my social media feeds and emails, and playing games for a couple of hours.

The handset also dealt surprisingly well with demanding tasks such as video streaming and 3D gaming. Streaming Netflix with the screen brightness at 75% the phone generally lost 12-15% of its charge per hour, which is above average. Many of the phones I review lose as much as 15-20% of their battery when streaming.

Gaming performance was equally impressive. Playing demanding games, like Riptide GP2 and Asphalt 0 the Idol 4S lost 18-22% of its battery. Most of the smartphones I test lose as much as 25% of their charge when gaming.

Should I buy the Alcatel Idol 4S?

The Alcatel Idol 4S is a well-built phone that offers reasonable performance and solid battery life. However, with pricing starting at $400 (£300) it’s a little overpriced. The OnePlus 3 is only £30 more and comes with better components.

I’m also not sold on the VR headset that comes bundled with it. The headset is too basic and feels like a gimmicky addition. I’d have preferred it if Alcatel dropped the VR headset and reduced the phone’s price.


The Alcatel Idol 4S is a solid mid-range phone that comes with a pointless VR headset.
