MT6582平台，手机待机后，电量的百分比不会更新？

MTK平台都有这个问题，需要修改休眠时的电量计算算法

具体怎么修改?

具体怎么修改啊?求教。

battery_meter.c 修改这个文件的resume函数，如下：

1. static int battery_meter_resume(struct platform_device *dev)
   
2. {
   
3. #if defined(CONFIG_POWER_EXT)

8. //    kal_int32 sw_vbat;
   
9. //    kal_int32 vbat_diff = 200;
   
10.         get_xtime_and_monotonic_and_sleep_offset(&xts, &tom, &rtc_time_after_sleep);
    
11.         _g_bat_sleep_total_time += rtc_time_after_sleep.tv_sec - g_rtc_time_before_sleep.tv_sec;
    
12.         battery_xlog_printk(BAT_LOG_CRTI, "[battery_meter_resume] sleep time = %d, g_spm_timer = %d\n", _g_bat_sleep_total_time, g_spm_timer);
    
13. 
    
14.         if (_g_bat_sleep_total_time < g_spm_timer) {
    
15.                 return 0;
    
16.         }
    
17. 
    
18.         bat_spm_timeout = true;

你这是MT6580的修改方案吧

具体问题要看LOG

我在80平台也遇到了电量下降很快的问题(休眠后)，一分钟降一个百分比。通过那样修改后编译个boot下载进去，还是会降的很快。难道是要全下吗。主要是uisoc和soc有时相差很大
